It is advisable to visually check the tires after each run.
When used for long periods in an intensive manner on circuits, please be aware that damage can occur to the tire and its carcass from regularly running over the curbing at the edges of the circuit. Camber values for road use must be based upon the recommended road settings to ensure the correct handling and behavior for both the vehicle and the tires.Īlways check the wear of your MICHELIN ® Pilot® Sport Cup 2 R tires and remaining tread depths, which should be at least at 1.6 mm. On the track, geometry settings (camber primarily) can be modified to improve cornering speeds and grip through maximizing the tire footprint and also to prevent excessive wear/fatigue to the outer shoulder.Ĭamber : for optimal results on a circuit, the negative camber settings should be between -1.5° & -3° dependent upon the circuit layout and the type of vehicle. The best performance is obtained with the grip of the tread pattern and not by running on the sidewalls. In this case, re-set the pressure to at least a minimum of +0.2 bar (+ 3 psi) to increase grip and maximize track longevity. Regularly check the external sidewalls: if you notice any level of wear, such as disappearance of the sidewalls markings, this can be a sign that inflation/operating pressures are too low.
To optimize the track longevity, Michelin ® strongly recommends to use a minimum inflation pressure that falls between 2.0 (29 psi) and 2.4 bar (35 psi) However, some vehicle models will need a higher inflation pressure than 2.7 bar (39 psi when hot).ĬOLD TIRES: It is not recommended to run inflation pressure below 1.9 bar (28 psi) when cold. HOT TIRES: The best operating pressure for MICHELIN ® Pilot® Sport Cup 2 R tires is between 2.3 bar (33 psi) and 2.7 bar (39 psi) when hot, depending on the vehicle model and track.
After a steady run of laps, check and only then adjust the inflation pressure to reach the best operating level: TRACK USE - For a track day, begin with inflation pressures recommended for ROAD USE, then gradually bring MICHELIN ® Pilot® Sport Cup 2 R tires up to temperature. ROAD USE - Adhere to the inflation pressures recommended by the car manufacturer. Make sure as well that the vehicle assistance systems are switched on.Īs a special tire for extreme dry conditions, the MICHELIN ® Pilot ® Sport Cup 2 R requires a warm-up phase to reach optimal performance. Drive carefully and with reduced speeds on wet roads. On wet tracks or roads, track tires, especially in a worn state, can be highly impacted by hydroplaning. The MICHELIN ® Pilot ® Sport Cup 2 R is a DOT legal track tire optimized for DRY track use.
