Proxes R1R 225/45ZR15

Extreme Performance Summer Tires Years of grueling on-track experience set the performance standards high for this extreme-performance summer tire. Its aggressive, arrowhead tread design, extra-wide footprint, high-grip compound, and autocross-inspired casing design let you drive hard through the corners and quickly accelerate in the straightaways, well beyond the normal limitations of sports coupes and sedans.
