Toyo Proxes R888R Tire - 225/45ZR15 91W XL

The Toyo Proxes R888R is a DOT-approved competition tire, sold as the evolution of the original Proxes R888. It pairs a high-grip race compound, which Toyo says comes up to working temperature quickly and stays consistent, with an asymmetric tread designed to split the work: large outer shoulder blocks handle cornering loads, a wide center rib handles braking and acceleration, and a water evacuation channel helps move water out of the contact patch.

Because the tread is asymmetric, the tires can be cross-rotated, which Toyo says helps reduce irregular wear over a season.

Specifications for this tire: size 225/45ZR15 91W XL; fits 15-inch wheels; section width 225 mm; aspect ratio 45; load index 91; speed rating W; overall diameter about 23.0 in (584 mm). Extra Load (XL) construction. Part number toy107820.
