235/64/18 GoodYear Wet Slick TYRE

1. Product introduction

The GoodYear CR9000 TC 01W3 tyre in size 235/640R18 is a wet competition tyre, previously marketed under the Dunlop brand. Designed for circuit use, it is aimed at drivers and teams seeking high-performance tyres in wet conditions, with a W3 compound specifically developed for grip on wet tracks.

2. Role of the part

The wet tyre plays an essential role in traction, braking, driving precision and water evacuation on circuit. Its tread pattern and soft compound help maintain contact with the track when rain significantly reduces grip. It contributes directly to vehicle stability, driver confidence and lap performance in wet conditions.

3. Symptoms or consequences of a worn or faulty part

• Loss of grip on damp or waterlogged tracks.
• Longer braking distances.
• Increased risk of aquaplaning in standing water.
• Reduced precision on corner entry and exit.
• Reduced lap time performance.
• Unstable handling if the compound is aged, hardened or unevenly worn.

4. Benefits of replacement

• Improved grip on wet tracks.
• Better water evacuation thanks to a rain-suited design.
• Optimised traction under acceleration.
• More stable and effective braking in wet conditions.
• More predictable vehicle handling under cornering loads.
• Product suited to competition and trackday use on circuit.
