ASPHALT TYRE FOR CLASSIC RALLY CAR. FOR ROAD USE TOO

The exclusive tread of the P7™ CORSA Classic incorporates two specific designs: slick for dry conditions and grooved for the wet, drawing on and developing the asymmetrical pattern that has characterised the very best Pirelli UHP tyres. An extraordinary formula to transform the tyre’s multipurpose aspect into grip:
• outer semi-slick for maximum lateral grip in the dry and solid centre rib to ensure precise trajectories with one’s foot down
• generous inner tread block pattern with grooves to channel water away from the contact patch.
The unique feature of the P7™ CORSA Classic is its versatility. With a single tread pattern, maximum performance is guaranteed under all weather conditions without compromising aesthetic appearance or driving comfort. The product is available in three different compounds for made-to-measure solutions under dry, damp or wet conditions. The P7™ CORSA Classic sidewall imitates the style of the original tyre from the late 70s. It now features a double set of markings with corresponding road size: a necessity due to the type approval required in order to be able to take part in championship races. The sizes in the P7™ CORSA Classic range offer the sizes established during the 70s: a Pirelli exclusive for the fitment of the original sizes to some of the most prestigious vehicle models that were at the time actually developed in cooperation with Pirelli. In particular, P7™ CORSA Classic is also available with a 16” rim diameter as originally adopted by the Lancia Rally 037 and Delta S4.

TYRE IDENTIFICATION FITMENT PRESSURE COMPOUND
Tyre identification

The markings that appears on the side of the tyres also tells us the basic size of the tyre, the rim diameter and the width of the rim.
We will illustrate how to read two different types of branding that may appear on the side of the rally tyres.

C: Nominal section width expressed in mm - 225
D: Nominal external diameter expressed in mm - 600
d: Nominal rim diameter of the rim, expressed in inches - 16
C: Nominal section width expressed in mm - 205
h/C: Tyre’s technical series. This expresses the ration between the section height (in mm) and the nominal section width (in mm) - 65
Radial construction - R
d: Nominal rim diameter of the rim, expressed in inches - 15

Fitment

Make sure that tyres are fitted by experts, with specialised dedicated machinery and equipment, who follow safety procedures.
Before mounting the tyres clean the surface of the beads and the area of the rim that comes into contact with the tyre.

Use ONLY special tyre lubricants for mounting tyres. Do NOT use silicone or petroleum lubricants.

Check the state of the valves to prevent air loss: Check the seals and the tightness for metal ones and check also for any tears or cracks in rubber seals. If necessary, replace them. When the tyre is being used, always use the valve cover top.

Follow the indications provided on the sidewall of the tyre referring to the rolling direction and the correct positioning of the internal and external sidewalls, if specified.

Use the safety cage when inflating tyres.
Before unseating the tyre from the rim during disassembly, make sure that the tyre has been fully deflated, removing the inner valve mechanism.

Pressure
Working pressure values depend on the size of the tyre in relation to the load that it is subjected to. In other words, it will vary according to the type of car, the weight and conditions of use.

In particular, as the weight of the vehicle, speeds and accelerations that the tyre is subjected to increase, the working pressure must be increased. In any case, tyres should not be used at pressures below 1.6 bar.

Using excessively low pressures would bring about the breaking of the tyre due to excess force on the sidewall or unseating from the rim. “Hot” working pressures are usually in the range of 2.2 – 2.5 bar.

Initial inflation pressures vary in order to obtain these values, depending on whether the tyres are preheated or used “cold”. Indeed, preheated tyres can be inflated to slightly lower values than cold tyres. 

The difference will depend on the type of heater, the time it remains and the environmental conditions.
