285/680/18 GoodYear Slick Rain tyre GT4

Product introduction

The GoodYear CR9000 Wet Slick 285/680R18 GT4 tyre is a competition tyre intended for circuit use in wet or rainy conditions. Previously marketed under the Dunlop brand, this GoodYear wet tyre is designed to deliver high grip, traction and precision on wet tracks, particularly for GT and GT4 category vehicles.

Role of the part

The wet tyre provides contact between the vehicle and the track when water significantly reduces grip. Its specific tread pattern effectively evacuates water from beneath the tread to limit aquaplaning, improve braking stability and maintain good traction on corner exit. Size 285/680R18 is suited to wide fitments used in GT car competition.

Symptoms or consequences of a worn or unsuitable tyre

• Loss of grip on wet or waterlogged tracks
• Increased risk of aquaplaning at high speed
• Longer braking distances
• Lack of traction under acceleration
• Reduced driving precision and stability under cornering loads
• Uneven wear that may reduce performance over stints

Benefits of replacement

• Restores optimal grip in rainy conditions
• Better water evacuation thanks to a competition-specific tread
• Improved driver confidence on wet tracks
• More consistent handling during braking, turn-in and acceleration
• Suited to the demands of GT4 driving sessions, testing and competition
• Available in W2 and W3 compounds depending on track conditions and temperature
