PIRELLI TIRE KNOWLEDGE
With over one hundred years of experience in tire technology, Pirelli guarantees the highest standards of security, longevity, comfort and attention to the environment amongst all products.
Each Pirelli tire provides not only performance, but also a "feel for the road,” allowing for a better understanding of the vehicle’s performance.
In addition to the Tire Size Designation a tire may be identified by a Service Description consisting of a Load Index (or two in the case of single/dual fitment) and a Speed Symbol.
The Speed Symbol indicates the maximum speed at which the tire can carry a load corresponding to its Load Index (except for loads at speed above 210 Km/h) under service conditions specified by the tire manufacturer.
The Load Index is a numerical code associated with the maximum load a tire can carry at the maximum cold inflation pressure (except for loads at speeds above 210 Km/h) at a speed indicated its speed indicated by the speed symbol under service conditions specified by the tire manufacturer.
YOUR SAFETY ON THE ROAD
Observe the rules of the highway code, always be careful and show respect for other drivers. Here is some good advice for driving safely, saving mechanics’ fees, tires and fuel. For fans of sports driving only one thought is needed: the road is not the racetrack. That said, here is some useful advice from the point of view of road safety.
One of the greatest risks of driving in the wet is aquaplaning: how can you counter this phenomenon?
Aquaplaning leads to “floating” of the tire and immediate loss of grip.
It is a dangerous situation which is typically created by tackling very wet stretches of road or large puddles of water, created by bad road surface drainage, at speed.
At these times, the grooves of the tread don’t manage to expel the water under the tire and, in practice, you can suddenly find the car “floating”.
With careful driving and tires which are not worn and are correctly inflated this danger can, on most occasions, be avoided, since treads are designed to drain the greatest possible quantity of water to ensure the best possible adherence.
Now that we’ve clarified the concept of aquaplaning here is some advice on how to cope with this situation.
Braking is no use because the car is floating and moreover there is also the risk, as soon as the tires grip again, that the car may swerve suddenly making you lose control completely.
The best thing to do is keep a firm grip on the steering wheel to prepare for "regripping" trying to keep the correct steering direction for the entire duration of the phenomenon and take your foot gradually off the accelerator pedal given that the engine revs increase rapidly as soon as the car starts floating.
The first thing: without chains or winter tires you won’t manage to go anywhere. The car will have no traction and on braking will be uncontrollable.
Observe the rules of the road scrupulously and be tolerant of drivers in difficulty who are going slower than you.
Increase the distance between your car and the one in front.
To reduce the risk of sliding while going uphill you can use a higher gear than you would use normally in the dry.
When driving avoid sharp acceleration, sudden steering action or braking, to minimise loss of traction on snow or ice.
For optimum performance and safety, it is essential for all four tires to be the same. Always use four winter tires of the same brand, and with the same construction features. Fit tires of the same size on the same axle, with the same characteristics of use, tread pattern and conditions of wear.
The use of studded tires, where permitted, must be extended to all four wheels. Consult the vehicle handbook for the correct load capacity and speed rating of the tires to be used.
Inflation pressures must be checked regularly and carried out when the tires are cold. If necessary correct the pressure, again when the tire is cold. Keep to the pressures indicated by the vehicle manufacturer. Note, pressures change in relation to the external temperature: a pressure of 2.0 bar measured at +20°C decreases to 1.74 bar at -5°C and falls to 1.59 bar when the temperature is at -20°C (a change of 20%).
Pay attention to the speed limit indicated by the rating on the tire sidewall. Optionally, the car may be equipped with tires of a lower rating than that prescribed, adjusting the speed. In this case, the regulations state that the reduction in speed must be indicated on an adhesive label placed inside the car (on the windscreen or dashboard so that it’s always visible to the driver).
The performance of winter tires remains effective down to a tread depth of 5/32mm. Below this level they are no longer adequate for winter use but can be used as summer tires down to the main tread minimum legal limit, set at 2/32mm.
When winter tires are not being used, they should preferably be kept on wheel rims and inflated, and the pressures checked regularly. If stored without rims, they must be stacked on their sides no more than four per stack so that they are not deformed by the weight.
Rotate winter tires in the right direction every 6,000/7,000 km.
"Green Performance" technology means fuel consumption could be reduced and environmental impact limited. But a lot depends on your driving habits. Here is some practical advice on how to make the most of the money saving opportunities presented by Pirelli “Green Performance” products.
Everyone knows that… you don’t brake on bends. And yet – pay attention observing the drivers in front of you – practically everyone comes into bends braking, before “letting go” of the pedal when they reach the centre of the bend. And everyone feels that they are perfect drivers since “you don’t brake on bends”.
It’s a shame that all the stage of establishing the trajectory has occurred with the brakes on.
Driving this way subjects the tires – above all the front ones – to a double exertion: maintaining the trajectory set and – in addition – resisting the force of the braking system.
All in a play of forces that can also endanger the stability of the car (and therefore the roadholding).
For this reason it is fundamental to brake sooner, slow down in time and – above all – brake as much as possible with the wheels straight. Doing it this way takes advantage of the maximum adherence possible offered by the tire before steering.
Safe and successful off-roading is a combination of knowledge and skill. Understanding specific techniques for different conditions and realising the capabilities and limitations of your vehicle are critical, but the final factor is the tires on your vehicle.
Tires can often make the difference between getting out of a tough situation or getting stuck. The following information is designed to ensure that you get the maximum performance from your Pirelli tires. If in doubt, always survey your chosen route on foot. In mud or other difficult conditions move off slowly and avoid spinning the wheels. Undue wheel spinning will cause the vehicle to slip and will fill the tire treads with mud.
When approaching soft muddy ground build up speed in low ratio 2nd or 3rd, trying not to spin the wheels by extreme acceleration. Go too fast and you risk bouncing and losing control, too slow and you will loose momentum.
In severe mud the most difficult situations are where the ground has rutted channels and axle deep pits.
Try to straddle the ruts if they are too deep to drive in – this will avoid dragging the diffs through the mud, which will reduce momentum and probably leave your vehicle stuck. Always try to maintain a steady momentum.
When driving in ruts, vary the accelerator and move the steering wheel from side to side- this allows the lugs on the shoulders of the tires to grip and bite into the sides of the ruts.
Never try to steer out of the ruts, let the steering wheel find its own way.
Whenever possible, check you wheel arches to make sure that they are not clogged with mud, this clogging will stop the tres from cleaning the mud from their treads.
For most types of off-road driving it is possible to maintain your normal road pressures. However, in severe conditions It is permissible to lower pressures to increase the tyre footprint and flotation ability.
NB: Never use the tyre pressures below 16psi. Re-inflate the tyres as soon as possible. On route to the service point,drive slowly, and under no circumstances exceed 50mph.
In light snow conditions the tires will break through the crust and grip on the surface below.
Use high range ratio and avoid revving the engine, go into low range and use a very light throttle, this will encourage the tires to bite and grip rather than slip.
In very severe conditions it may be necessary to fit chains.
For most types of off-road driving it is possible to maintain your normal road pressures. However, in severe conditions It is permissible to lower pressures to increase the tire footprint and flotation ability.
NB: Never use the tire pressures below 16psi. Re-inflate the tires as soon as possible. On route to the service point,drive slowly, and under no circumstances exceed 50mph.
The skill in tackling rock conditions is to keep to the high ground wherever possible in order to avoid damage to the diffs, transmission or skidplates.
Torque is more important than power in climbing rock slopes, thus first or second gear in low range is best.
Use light throttle to prevent tire slipping.
For most types of off-road driving it is possible to maintain your normal road pressures. However, in severe conditions It is permissible to lower pressures to increase the tire footprint and flotation ability.
NB: Never use the tire pressures below 16psi. Re-inflate the tires as soon as possible. On route to the service point,drive slowly, and under no circumstances exceed 50mph.
For loose sand select high range four wheel drive – this will maintain speed, if, however the vehicle bogs down, move into low range.
Soft, loose sand is traction sapping and requires continual momentum, often using full throttle.
For most types of off-road driving it is possible to maintain your normal road pressures. However, in severe conditions It is permissible to lower pressures to increase the tire footprint and flotation ability.
NB: Never use the tire pressures below 16psi. Re-inflate the tires as soon as possible. On route to the service point,drive slowly, and under no circumstances exceed 50mph.
When negotiating water it is important that your electrical system is protected. Silicon based grease on vulnerable items is a good idea. It is absolutely vital that your air intake will be clear of the water. Ingress into the engine is terminal and expensive. Before tackling a water crossing it is critical to survey the course.
Consider:
• The river flow, fast flowing means clean silt-free water. Slow moving may mean soft deep silt.
• Check the depth of water and any silt with a spade or similar. Also check for holes or large rocks which may impede your progress.
• Look closely at the entry and exit banks, bear in mind on exit you will have little momentum.
• When entering the water select low 2nd gear.
Creating a bow wave means the water in front of the vehicle is deeper but a trough is created behind the wave, i.e. in the engine bay.
If you go too fast the bow wave will break over the hood losing the trough effect in the engine bay.
When clear of water always drive a short distance with the footbrake lightly depressed to restore braking efficiency.
Check your radiator is clear of mud and leaves, and of course check for damage to your tires, as you will not have been able to see any potential damaging underwater obstacles.

TIRES LONG LIFE
For your safety it is important to check your tyres regularly, at least once a month. Look for signs of damage or uneven wear because improper inflation pressures, misalignment, improper balance, or suspension malfunctions can affect the overall performance of your Pirelli tire and endanger your safety. Always ask your nearest Pirelli tire dealer for a check and assistance. Tires are the only point of contact between your car and the road: so keep them in good shape.
The correct maintenance of your tires is a priceless operation. Air is totally free and correct inflation pressure is the main secret for a longer 'lifetime' for your tires.
Insufficient inflation pressure is the main cause of tire damage.
Extended lifetime and, as a result, excellent performance for a longer period of time, means concrete economic benefits, due to savings in tire replacement costs and lower fuel consumption.
Correct inflation pressure also improves vehicle manoeuvrability, reducing the 'braking distance'.
A monthly check up is sufficient to keep the tires at the correct inflation pressure.
It is a quick, yet fundamental way to control the health of your tires and is important for your driving safety.
Check the inflation pressure on 'cold' tires. Here are the steps to follow:
Performance and driving safety are two key elements for Pirelli, that’s why we would like to share with you some small actions that will help you drive in total peace of mind and safety.
Tire rotation is a simple and effective way to prolong the useful life of tires by achieving more uniform wear.
PERFORMANCE, SAFETY, PEACE OF MIND
Run Flat tires mean safety. They provide greater control of your car in emergency conditions and allow you to continue driving safely even during a rapid loss of inflation pressure.
With Run Flat, you will retain mobility in the event of a puncture. So, if your tire is punctured, even in pouring rain, the Pirelli Self-Supporting Run Flat means you don't have to bother with the spare. Instead, you can continue driving for a limited period.
To ensure maximum safety during an emergency situation, the Run Flat tyre must maintain certain speed and distance parameters (80km/h for 80km or 50mph for 50 miles). Due to these restrictions, it's imperative that motorists be notified when a loss in tire pressure occurs, and therefore the vehicle must be equipped with a TPMS (Tire Pressure Monitoring System) to detect and signal tire pressure changes.
OPERATING REQUIREMENT
Run Flat tires have been developed based on the specifications of the vehicles on which they are mounted. Accordingly, Run Flat tires may only be mounted on vehicles specifically manufactured to accommodate Run Flat tires.
Run Flat tires must be mounted in conjunction with a functional Tire Pressure Monitoring System (TPMS). The mounting of tires and installation of the TPMS should be carried out by a specialised dealer.
Pirelli certifies that after pressure loss, Run Flat tyres can continue to run for 80km (50 miles) at a maximum speed of 80km/h (50 mph). Always refer to the vehicle owner's manual for specific safety and operating information relating to the vehicle.
After the low pressure warning is shown, the condition of the remaining tires and the TPMS should be checked immediately by a specialised dealer.
A tire should always be changed and not repaired after a loss of pressure, as it is not always possible to establish the time and conditions under which the tire has been used with insufficient inflation pressure.
Damaged Run Flat tires, or Run Flat tires that have experienced a loss of pressure should be replaced immediately with another Run Flat tire of identical size and service description (Load Index and Speed Code). Pirelli recommends that a tire of a different type, or which contains a different load index or speed code, should never be mounted on the same vehicle.
After a loss of pressure, the rims should be inspected to ensure they haven't been damaged. Damaged or deformed rims should always be replaced prior to mounting a new Run Flat tire. Pirelli recommends the use of Extended Hump rims (EH2), which reduce the risk of bead unseating in case of loss of pressure.
Yes it is possible, although Pirelli strongly recommends that EH2 rims be used because they guarantee improved retention of the tire bead down to zero inflation pressure. In the event of run flat operation at zero pressure with H2 rims, provided that a Pirelli self-supporting run flat tire is used in conjunction with a Tire Pressure Monitoring System (TPMS) or air pressure warning system, the tire will maintain its run flat characteristics. A TPMS is absolutely necessary to alert the driver that the tire has lost pressure.
Standard tires can be fitted to EH2 rims but they will not have run flat features.
Pirelli does not recommend mixing run flat tires and standard tires on the same vehicle, even if paired in axle sets. If you have a puncture, the run flat tires are designed to permit you to reach a tyre dealer where you can have the tire checked and replaced if necessary with another run flat tire. In exceptional and emergency circumstances a normal tire with identical dimensions, load index and speed code can be fitted for a very limited period and distance. It must be noted that standard tires do not have the same run flat characteristics as the other tires on your vehicle and must be removed at the earliest opportunity.
Yes, but Pirelli recommends that in a run flat condition you should not exceed 80km (50 miles) at a maximum speed of 80km/h (50 mph). Pirelli strongly recommends that the different tire brands should be fitted in axle sets and the tire pressure monitoring system must be controlled to make sure that the pressure settings are compatible.
Run Flat tires have been developed based on the specifications of the vehicles on which they are mounted. Accordingly, Run Flat tires may only be mounted on vehicles specifically manufactured to accommodate Run Flat tires, therefore you must contact the vehicle manufacturer if you are in doubt.
No, for safety reasons, Pirelli chooses not to recommend the repair of self-supporting run flat tyres. A self-supporting run flat tire should always be changed and not repaired after a loss of pressure because it is not always possible to establish the time and conditions under which the tire has been used with insufficient inflation pressure.
Yes.
No. After a puncture you can only travel 80km (50 miles) at a maximum speed of 80km/h (50mph), following which the tire must be replaced.
Provided the vehicle is operated within restricted run flat speed of 80km/h (50 mph), handling is only slightly impaired due to reduced cornering force. Aquaplaning and braking remain almost the same. It is recommended that you avoid sharp driving manoeuvres if a tire is completely deflated, especially if the tires are fitted to H2 standard rims.
No. The maximum condition guaranteed by Pirelli is 80km (50 miles) at zero pressure at a speed not exceeding 80km/h (50mph). For vehicles fitted with Pirelli self-supporting Run Flat tires as original equipment, the tire manufacturer's recommendations indicated in the owners manual apply.
There are a range of tire pressure monitoring systems (TPMS) available so you should consult the vehicle manufacturer if you require a specific explanation. Basically there are two types of system, indirect systems use the fact that reduced air pressure causes the wheel to rotate at a slower speed and when they detect this difference send a warning to the driver. Direct systems directly control tire pressure against pre-set values and send a warning when actual pressure falls below set values.
which appears on the sidewall of the tyre. On tires specifically homologated for BMW vehicles there are also the letters RSC which stand for Run Flat System Component.
Pirelli guarantee a general maximum distance of 80km for all self-supporting run flat tyres. Vehicle manufacturers conduct their own tests based on specific vehicle models, taking into consideration vehicle weight and characteristics and can decide together with the tire manufacturer can suggest an increased distance for that specific vehicle. For vehicles fitted with Pirelli self-supporting Run Flat tires as original equipment, the tire manufacturer's recommendations indicated in the owners manual apply.
Pirelli introduces on the market its new “Seal Inside Technology”, the new concept of extended mobility to safely drive your cars in the event of a puncture.
Seal Inside (S.I.) is a new tyre construction technology that allows you to drive on without losing air pressure even after the tyre has been punctured by an external object, covering almost 85% of the possible accidental causes of pressure loss*.
The Seal Inside logo will be used to identify all Pirelli products featuring this new technology.
The logo (in black) is also on the tyre sidewall.
* The Seal Inside is effective for the majority of the punctures apart from the ones that are compromising the integrity of the tyre
Inside the tyre, in the area corresponding to the tread pattern, a sealing layer material tightly blocks every possible air leakage in case of a puncture that passes through the carcass with or without an external object still present.
The Seal Inside deals immediately with the hole and its fast and effective action, in most cases, does not make the driver realize that the tyre has been punctured.
In the event of a puncture, the sealant allows the driver to continue driving – not having to stop the vehicle for an immediate replacement of the tyre – until it can be replaced.
The sealant does not guarantee permanent repair of the tyre caused by a puncture. For this reason Pirelli recommends that drivers regularly monitor the tyres in order to identify punctures that are sealed, or the presence of nails or screws on the tread pattern. In such a situation, it is necessary to go to a specialized tyre dealer who can identify the puncture area and remove the object that caused it.
The tyre dealer has to subsequently evaluate the extent of the damage and decide if the tyre can be repaired or not.
Seal Inside tyres can significantly reduce the chance of having a flat tyre but, unlike run flat tyres, are not designed to be driven under inflated or in a flat condition.
In terms of mounting, removing and balancing there are no differences between Seal Inside and standard tyres. Pirelli tyres with Seal Inside technology do not need dedicated rims and for this reason can be mounted on the same standard rims used for standard tyres.
Seal Inside tyres should be stored in the same conditions recommended for standard tyres.
Premise: examination of a damaged tyre and execution of a proper repair are the responsibilities only of a specialized tyre dealer. Pirelli does not assume any liability for operations performed by third parties.
To perform the repair of a tyre with Seal Inside technology it is necessary to remove the layer of sealant in the puncture area within the tyre until you reach the impermeable butyl layer, for an area with the same size as the repair patch to be applied; after removing the sealant the repair operation is equivalent to that of a standard tubeless tyre.
As is evident, this operation to remove the sealant from the puncture area inevitably means that the treated area loses the special technical feature of Seal Inside.
Within a product line there is no difference in terms of driving performance (rolling resistance, comfort, noise, dry and wet performance) between a Seal Inside tyre and a standard tyre.
The Seal Inside Technology does not need dedicated rims and TPMS (Tyre Pressure Monitoring System) to be used safely on a vehicle; it can be used on any kind of vehicle depending on the tyre size.
DISCOVER THE TIRE MARKINGS
In addition to the tire size and the service description, on the tire sidewall there are several different inscriptions: let's have a look at some of them.
This example shows a typical tubeless radial tire.
For all asymmetric products it is important to fit the tire on the rim in the correct position. In fact asymmetric tread pattern designs are developed to offer the best performance considering the different behaviours of the external and internal areas of the tread design.
DOT (Department Of Transportation) is a legal marking required in many countries in order to sell the tyres. DOT means the tires meet or exceed the Department of Transportation’s safety standards.
1) Means tire meets or exceeds Department of Transportation safety standards
2) Manufacturer and Plant Code Number (Assigned by DOT)
3) Tire Size Code Number
4) Group of Optional Symbols for the Manufacturer ( To identify the brand or other significant characteristics of the tire)
5) Date of manufacture
When a tire bears the ECE symbol, this means it is ECE certified and approved to meet ECE standards for physical dimensions, branding requirements and high speed endurance regulations. The marking is made up of the letter E and a number representing the country releasing the approval sheet, followed by a unique number combination for each product.
When a tire bears the European Noise Approved number this means it is compliant with Directive 2001/43/EC, respecting the new noise emission levels set for the European countries.
UTQG is a standard defined by the DOT of the USA for grading the performances of tires in the areas of TREADWEAR, TRACTION and TEMPERATURE RESISTANCE. It applies only to car tires with a rim diameter of 13" and larger, but not to winter tires.
TREADWEAR: The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
TRACTION: The traction grades, from highest to lowest, are AA, A, B, and C. These grades represent the tyre's ability to stop on wet roads as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tyre marked C may have poor traction performance. Caution: the traction grade assigned to the tyre is based on straight-ahead braking traction tests, and does not include acceleration, cornering, aquaplaning, or peak traction characteristics.
TEMPERATURE: The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. Grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Caution: the temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, under inflated tires, or excessive loads, either separately or in combination can cause heat build-up and possible tire failure.
TWI is an important safety feature that easily allows how much tread is left on the tire to be verified. Narrow bars of rubber are moulded at a height of 1.6 mm (2/32”) across the bottom of the tread grooves. When the tread wears down to these bars, the tire should be replaced.
Winter tires, also called snow, cold weather or thermal tires, and identified by the branding M+S (Mud&Snow) on the side of the tires together with the drawing of a mountain with a snowflake. Legally the M+S marking alone is sufficient to identify a winter tyre, but the tire industry has adopted the snowflake marking to differentiate real winter tires (M+S and snowflake) from all-season tires (only M+S).
WHAT IS WARRANTED AND WHO IS ELIGIBLE UNDER THE WARRANTY?

CAUTION
Pirelli wishes to emphasize that, because of specific regulations in various countries and possible amendments to technical and legal prescriptions, it is necessary to ensure that, before fitting the suggested tires, the selected fitting is allowed by the technical characteristics of the vehicle and by the vehicle manufacturer and that the fitting is in compliance with the applicable homologations.
Pirelli takes no position on the reliability of the wheel/tire combination as it relates to the technical specifications for the chassis and vehicle.
New technologies and increasingly advanced technical characteristics, a continuous research towards safety, a jurisdiction not easy to understand: the tire sector is facing a continuous evolution and working your way through it can be very difficult. The aim of this section is to facilitate the understanding of product technicalities and to provide useful information about tires and their safety aspects. Tire Pairing It is strongly recommended that Pirelli tires be mounted in sets of four with the same tread type. Pirelli tires should not be mixed with other tire brands. It is necessary to follow this procedure because of different tire constructions and different tire slip angles. When changing only two tires on a vehicle which is homogeneously fitted (four tires the same tire size), fit the new tires on the rear axle. This applies to all vehicles regardless of their drive axle (Front or Rear Wheel Drive). Remember on all wheel drive vehicles the tires must always be replaced in sets of four.
If a Run Flat tire becomes unserviceable due to workmanship or materials anomalies or road hazard injury during the initial warranty period, which is one year from the date of original retail purchase of the vehicle or purchase of replacement tires (purchase receipt required) or within the first 2/32” (1.6mm) of the original usable tread, whichever occurs first, the tire will be replaced to the owner at no charge for the tire.
After the initial warranty period, if a Run Flat tire becomes unserviceable due to workmanship or materials anomalies or road hazard injury, the owner must pay the cost of a comparable new Pirelli brand or PTI private brand replacement tire on a pro-rata basis. The authorized Pirelli dealer will determine the cost by multiplying the percentage of the original usable tread worn by the current dealer selling price. The owner must pay for any associated service charges, including mounting and balancing of the tire.

Original New Tire Tread Depths (Top Row)
How to Determine Percent of Tread Worn
Obtain the original tread depth of the new tire
In the groove closest to the center, measure the used tire to determine the tread remaining in 32nds of an inch.
The percentage worn is indicated where the tread remaining line (above chart) meets the original new tread depth column.
To determine the adjustment charge, multiply the percentage of tread worn by the current dealer retail selling price.
