GoodYear Slick Rain 305/660/18 W2 tyre for prototype circuit use

The GoodYear Slick Rain tyre 305/660/18, formerly marketed under the Dunlop brand, is a competition tyre designed for prototypes and racing vehicles operating on wet circuits. From the Slick Pluie range, it offers optimal traction, excellent water evacuation and a high level of precision in wet conditions.

Purpose of the part

The tyre is the only point of contact between the vehicle and the track. In rain configuration, its role is to ensure grip, stability when braking, traction when exiting corners and control of the vehicle despite the presence of water on the driving surface. Its W2 compound is specifically developed to offer consistent performance on wet to wet tracks.

Symptoms or consequences of a worn or unsuitable tire

• Loss of grip on a wet track
• Longer braking distances
• Risque accru d’aquaplaning
• Lack of traction when accelerating
• Degradation of driving precision
• Irregular wear or drop in relay performance

Benefits of replacement

• Restoration of grip on wet tracks
• Better water evacuation thanks to a suitable tread
• Gain in safety and confidence in rainy conditions
• More stable behavior when braking and supporting
• Performance optimised for competition use
• Adapted to the requirements of prototypes and circuit racing vehicles
