This high performance tyre is optimised for high speeds, giving motorists excellent grip and both wet and dry conditions.

The Dimax R8+ is also suitable for EVs, with EV compatible size variants featuring a special low rolling resistance compound.

Great Handling at High Speeds

An exceptional tyre for the price. Swapped my Pilot Sports for these and not disappointed. Mpg slightly reduced, but nothing in comparison to the £800 saving I made.

Perform well in all conditions. Good feedback and wear rate is very good. Why would you waste money on other more advertised brands…?
