Toyo Proxes R888R Tire - 235/35ZR19 91Y

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 235/35ZR19 91Y; fits 19-inch wheels; section width 235 mm; aspect ratio 35; load index 91; speed rating Y; overall diameter about 25.5 in (647 mm). Part number toy103840.

IMPORTANT: Competition use only. Toyo states the Proxes R888R is intended for competition events, not for everyday street use. Operating-temperature, inflation and alignment recommendations are published by Toyo on the product page for this tire. Toyo publishes a cold-weather handling and storage advisory for its competition tires; read it before storing or moving these tires in freezing temperatures.
