305/660/18 GoodYear Slick Rain tyre GT4

1. Product introduction

The GoodYear 305/660/18 GT wet circuit tyre is a competition tyre developed for use on wet tracks. Previously sold under the Dunlop brand, this wet tyre is designed for GT and Touring Car racing vehicles requiring high levels of grip, traction and stability in damp conditions.

2. Role of the part

The role of a wet circuit tyre is to provide optimum contact between the vehicle and the track when the asphalt is damp or soaking wet. Its specific compound and tread pattern disperse water, limit aquaplaning and maintain high driving precision under braking, cornering loads and acceleration.

3. Symptoms or consequences of a worn or faulty part

A worn, hardened or unsuitable wet tyre can cause significant loss of grip, longer braking distances, reduced traction on corner exit and increased risk of aquaplaning. On circuits, this can also lead to reduced performance, unstable vehicle handling and uneven tread wear.

4. Benefits of replacement

• Improved grip on damp or soaking wet tracks
• Better water dispersal thanks to a design dedicated to wet conditions
• Reduced risk of aquaplaning in competition use
• More precise handling under braking, cornering loads and acceleration
• Performance suited to GT and Touring Car vehicles on circuits
• Ideal replacement for maintaining consistent grip in sports driving or competition
