The Dunlop SP Sport Maxx GT in size 265/30R20 94Y XL is a Maximum Performance summer tyre engineered for elite sports cars and high-output sedans. The R01 marking is a highly specific Audi Quattro (RS models) homologation, meaning this tyre was custom-tuned for the steering geometry and all-wheel-drive dynamics of vehicles like the Audi RS4 and RS5.

The (EU) designation confirms it was produced in Dunlop’s premier European facilities (typically Germany), where high-speed stability for the Autobahn is the primary engineering focus.
