Goodyear GT4 285/680R18 wet circuit slick tyre

The Goodyear GT4 285/680R18 wet circuit slick tyre, formerly marketed under the Dunlop brand, is a competition tyre developed to offer a high level of grip on wet tracks. Intended for GT4-category vehicles and racing cars used on circuits, it maintains traction, precision and stability when weather conditions become difficult.

Part function

The wet tyre maintains contact between the car and the track in damp conditions. Its specific tread and dedicated compounds effectively disperse water, limit losses of grip and maintain a suitable operating temperature. On a competition car, it directly contributes to braking performance, traction on corner exit and high-speed stability.

Symptoms or consequences of a worn or unsuitable tyre

• Loss of grip on wet tracks
• Longer braking distances
• Increased risk of aquaplaning
• Lack of precision on corner entry and exit
• Reduced lap-time performance
• Unstable handling during cornering or acceleration

Benefits of replacement

• Improved grip on wet circuits
• Better water dispersal thanks to the competition wet tread pattern
• Rapid warm-up with W2 and W3 compounds
• Enhanced high-speed stability
• Optimised traction in wet conditions
• More consistent handling during intensive stints
