The dedicated DOT approved race tire for racing enthusiasts that need extreme levels of performance when driving on track.
Developed for the most powerful sports cars in production, the P Zero™ Trofeo is the embodiment of the Pirelli experience in motorsport. Best suited for racetrack driving on dry asphalt, the P Zero™ Trofeo reacts with precision even under intense use and high temperatures. Even in the most demanding sessions, it ensures high levels of grip and constant trajectories.
Although engineered specifically for the racetrack, the P Zero™ Trofeo is also approved for road use, enabling travel to the track. In the event of wet asphalt, judicious driving at reduced speeds is advised to limit the risk of aquaplaning. The P Zero™ Trofeo is generally not recommended for use in wet track conditions.
The P Zero™ Trofeo was designed under the Green Performance philosophy and features environmentally friendly compounds free of potentially harmful highly aromatic oils. It also already meets pending legislation for reduced noise levels.
Developed for the racetrack
The asymmetric tread is characterized by two wide central ribs and large regular blocks.
Developed for the racetrack, each area has a specific function, calculated to the millimetre.
The inner area, together with the longitudinal grooves, responds to the critical issues of wet surfaces and aquaplaning.
The imposing central ribs guide the trajectories and withstand the structural stresses on braking.
The transversal cuts ensure traction and braking.
The outer area with pattern derived from rally asphalt applications, ensures the required rigidity to cope with the stresses during cornering, typical of racetrack driving.
A notable increase (+10%) in the size of the contact area in bends, thanks to flexibility derived from the numerous grooves present from the centre towards the inner shoulder.
In front (for cars with different sections on the axles) and all-around fitments, the longitudinal grooves are wider, to counter the effects of standing water, with respect to the rear tire.
front (where applicable, with narrower section): good performance in aquaplaning thanks to the land/sea ratio comparable to a pure road tire;
rear: thanks to the specific work done by the front tire, it can concentrate on road holding deriving from the ‘fuller’ pattern;
all around: intermediate solution, with a lower land/sea ratio than a pure road tire.
Work on grip, on contact pressure and on better driving controllability – the result of studies on tread patterns with road characteristics – give P Zero™ Trofeo the lead on laps in dry conditions.
Technology in the service of racetrack driving
Maximum response to the driver’s commands, high grip in bends, acceleration and braking: the design qualities of P Zero™ Trofeo transfer safety into extreme use and in road journeys. These results are thanks to manufacturing solutions which have increased structural resistance for extreme use of tires. P Zero™ Trofeo is a leader in technological refinement.
With respect to the previous product the design innovation of P Zero™ Trofeo stands out for the larger footprint with a more uniform distribution of the pressure. The advantage translates into greater grip, more regular wear and a increased driving comfort.
Pirelli has developed new formulas, in order to maintain high performance over longer times in the presence of very high thermal stresses, without penalizing handling on wet surfaces.
P Zero™ Trofeo has a quite stiff construction and does not usually require higher pressures for racetrack use. It is designed for use at a pressure of approximately 2 bar, to be adjusted according to the type of car.
The figures indicated refer to the “operating pressure”: the pressure of the tire when it is fully warmed up to working temperature. For accurate calibration, it is essential to consider that the difference in temperature between a “cold” tire and a “hot” one is quite significant, normally 0.5 bar.
Adjust the tire pressures when cold, setting the operating pressure required minus approximately 0.4 bar. Drive three or four laps of the track to bring the tires up to temperature, then come back into the pit-lane and immediately adjust the tire pressure to the operating pressure required.
It is advisable to continue to check the pressure “hot” during use.
Pirelli recommends the use of ordinary compressed air to inflate the tires, provided that the above procedures are followed. No special gases, such as nitrogen, are required unless the source of air is exposed to excessive humidity.
Always use a high-quality air pressure gauge in order to obtain reliable results. We also recommend that the valve stems of the wheels should be metal, instead of rubber, as they are more resistant to high temperatures.
After use on the track remember to re-set the pressures to conditions of normal use of the car
To bring the car to the track and obtain the maximum performance and safety it is naturally indispensable for the car to be in perfect efficiency.
Priority is to check the brakes, steering and suspension, which must be perfectly efficient.
On the occasion of “track days”, it is advisable to replace the brake pads with competition pads capable of withstanding the higher temperatures generated by the constant use that circuit driving demands.
It is important to use professionals also for the preparation and installation of the specialist safety equipment, such as the “full harness” seat belt, a competition seat, the roll bar, etc.
For the maximum safety in racetrack driving we also recommend an approved helmet and a specific driver’s suit: overalls, specific shoes and fireproof gloves.
