Internal Tests vs. its predecessor the MICHELIN Pilot Sport Cup 2 N0 tire equipped in 265 / 35R20 and 325 / 35R21
MICHELIN Pilot Sport Cup 2 R is a tyre (semi-slick) specifically designed for dry circuit use. However, this tyre complies with the regulations for use on the public domain of the countries in which it is distributed. This tyre has the required regulatory markings and approvals.
On wet circuit or wet road, especially in high water, there is a risk of aquaplaning common to all wide tyres and in particular, close to wear indicators. Also, to ride safely, reduce your speed and leave active safety and driver assistance systems active. For reasons of behaviour, the homogeneous mounting of 4 MICHELIN Pilot Sport Cup 2 R tyres is highly recommended.
Regularly monitor the condition of your tyres. Watch for the tread height of the MICHELIN Pilot Sport Cup 2 R tyres, which must always be greater than 1.6 mm in all points (wear indicators) and any damage. Watch for the appearance of the outer flanks: if you notice a beginning of wear on the flanks (like erasing the markings), it means that the pressure is TOO LOW. In this case, add at least 0.2 bar (3 psi) to increase the grip and maximize the life of the tyres. The best grip performance comes from the tread and in no case rolling on the sidewalls.
AFTER A SITTING CIRCUIT, AND BEFORE TAKING THE ROAD OPEN: Always check the condition of your tires in accordance with the legislation and / or the highway code (wear/damage). Wait for the cooling of the MICHELIN Pilot Sport Cup 2 R tyres and readjust the pressure in accordance with that recommended by the vehicle manufacturer (road use). Reconnect safety, driver assistance and pressure monitoring systems if they have been disconnected.
- USE ROAD: Comply strictly with the inflation pressures recommended by the vehicle manufacturer.
- CIRCUIT USE: IMPORTANT! For a circuit session, start with a gradual warm-up of the MICHELIN Pilot Sport Cup 2 R tyres while driving at a moderate pace, with road use pressures. After a few warm-up laps, adjust the inflation pressure very slightly to reach the optimum operating pressure.
The optimum operating inflation pressure of the MICHELIN Pilot Sport Cup 2 R tyres is between 2.3 bar (33 psi) and 2.7 bar (39 psi) when heated, depending on the vehicle and circuit. However, some vehicles require tyre inflation pressures in excess of 2.7 bar (39 psi) when hot.
Never lower the tyre pressure of MICHELIN Pilot Sport Cup 2 R tyres below 1.9 bar (28 psi). To maximize the longevity of MICHELIN Pilot Sport Cup 2 R tyres, Michelin strongly recommends a minimum cold inflation pressure of between 2.0 bar (29 psi) and 2.4 bar (35 psi).
If you do not use the MICHELIN Pilot Sport Cup 2 R tyres for a long time, remove them from the rims and deflate them to half their usual inflation pressure to store them. Store tires in a clean, dry place, protected from light and sources of ozone (electrical equipment), in accordance with advice from Michelin and at temperatures always above 0 ° C (32 ° F). ). Do not use, store, handle or transport MICHELIN Pilot Sport Cup 2 R tyres at ambient temperatures below -10 ° C (14 ° F). Under these conditions, the components of the tire can degrade, resulting in reduced performance, or even irreversible damage making the tyre unfit for use. Never use a tyre that has breaks/cracks/ other damage on the tread or on the sidewalls. If in doubt, consult a MICHELIN representative. When using an intensive circuit, damage may occur on your tyres in case of prolonged or too frequent running on the vibrators that mark the track of certain circuits. Also, it is necessary to visually inspect your tyres after each "run", before returning to the circuit. In the case of prolonged or frequent running on the vibrators, or an exit of the track, it is necessary to proceed to a more thorough examination of the tyres. In this case, disassembly of the tires will be necessary to examine both the exterior and the interior of the tyres by a professional.
On the track, the geometric adjustments (especially camber) can be modified: to improve the speed of the vehicle cornering, to improve the grip of the tyre by maximizing its footprint on the ground, to avoid rapid wear on the outer shoulders of tyres. Camber: For optimal use on the circuit, the camber (or negative camber) must be between -1.5 ° and -3 ° depending on the track and the vehicle. NEVER exceed -4 ° counter camber (or negative camber). The camber values must be returned to the "road" settings recommended by the manufacturer before leaving the circuit, in order to find a behaviour designed by the manufacturer and correct wear of the tyres.
