Great improvement from last year. Upgraded from Continental All-wheather tires (205/55/16) and the stock wheels to High Performance Summer tires Goodyear Eagle F1 GS-D3 (225/50/16) with Mille Miglia MM2 Sport wheels.
Close-up of tire wear after just two driving sessions (aprox 70 miles) at Road America.
Notice the melted rubber strips next to the grooves.
