P Zero™ Trofeo R - The track is your road.
An innovative ultra-low profile tyre, with asymmetric tread pattern.
Designed for racetrack driving on dry asphalt.
Developed to provide even greater performance - on the occasion of Track Days - when fitted to the most powerful vehicles such as Porsche, Ferrari, BMW, Lamborghini, including the MY2012.
With P Zero™ Trofeo R you can fully appreciate the performance of extreme vehicles in complete safety, especially on the track.
In extreme conditions, typical of racetrack driving, it reacts with precision to commands. On dry asphalt, even in the most demanding sessions it ensures high levels of grip and constant trajectories.
P Zero™ Trofeo R is not recommended for use in very wet track conditions.
Specific for racetrack driving, it is approved for road use, enabling travel to the track. In the event of very wet asphalt, with the risk of aquaplaning, prudent driving at reduced speed is recommended.
P Zero™ Trofeo R has brand new HAOF (highly aromatic oil free) compounds and a redesigned tread pattern that have produced extraordinary results: on the one hand, a notable improvement in stability and, above all lateral grip in the dry, on the other hand, a notable reduction in wear.
Developed for the racetrack
The asymmetric tread pattern is made of two areas:
The inner area, together with the longitudinal grooves, responds to the critical issues of wet surfaces and aquaplaning. The wide central ribs ensure precise trajectories and alleviate the stress of accelerating and braking on the track. The transversal grooves with special pattern provide constant traction and assist braking. The wide circumferential grooves enable water drainage, therefore maintaining traction in the wet.
The outer outer area ensures the required rigidity to cope with the stresses during cornering, typical of racetrack driving.
The solid shoulder - similar to a slick but more rigid - maximise lateral grip when cornering at very high speed and quickly changing trajectory on the track whilst maintaining complete control.
This special mix of shape/functionality has enabled the achievement of very consistent performance.
P Zero™ Trofeo R 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 tyre 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” tyre and a “hot” one is quite significant, normally 0.5 bar.
Adjust the tyre pressures when cold, setting the operating pressure required minus approximately 0.4 bar. Drive three or four laps of the track to bring the tyres up to temperature, then come back into the pit-lane and immediately adjust the tyre 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 tyres, 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.
