RGC 01 TW – Wet Semi Slick Tire for Track & Road

The RGC 01 TW is a specialized wet semi slick tire engineered for maximum grip, control, and safety in rainy and low-temperature conditions. Designed for drivers who demand performance regardless of the weather, this tire delivers motorsport-level wet traction while remaining fully legal for everyday road use.

Unmatched Performance in the Wet

The advanced tread pattern of the RGC 01 TW efficiently channels water away from the contact patch, dramatically reducing the risk of aquaplaning. Thanks to its optimized groove layout and rubber elasticity, the tire maintains excellent stability and traction even during heavy rainfall.

Precision Handling & Balanced Construction

Rounded shoulder and sidewall design – improves steering accuracy, smooth turn-in response, and predictable handling on slippery surfaces.
Even wear characteristics – the construction ensures consistent grip throughout the life of the tire, providing reliable performance lap after lap.
Motorsport-grade wet compound – designed to generate grip even when temperatures drop, making it perfect for unpredictable weather conditions.

WET-SuperSoft (rain super-soft) – suitable for temperatures from -10°C to 15°C.
WET-Soft (rain soft) – also suitable for wet surfaces.

Perfect for Track & Road

Whether you’re driving track days, rain sessions, hill climbs, supersprints, or simply need a safe and capable wet-performance tire for road use, the RGC 01 TW stands out as one of the most effective wet racing tires in the semi slick category.

Road Homologation

The tire carries European road homologation (E-mark), making it fully legal for public road use — a strong advantage for drivers who switch between road and track without needing separate tire sets.
