Toyo Proxes R Tire - 235/40ZR17 90W

The Toyo Proxes R is a DOT-marked competition tire for dry road racing and high-performance driving experiences (HPDE). It replaces the Proxes RR: Toyo says it is quicker and more predictable while keeping the RR's consistency and durability.

It uses a newly developed racing tread compound and all-new construction with a reinforced sidewall and a high-modulus bead filler, aimed at stability and steering response. The footprint is longer with more contact area, and the 4/32" tread includes wear inspection markers so you can read how the tire is wearing.

Specifications for this tire: size 235/40ZR17 90W; fits 17-inch wheels; section width 235 mm; aspect ratio 40; load index 90; speed rating W; overall diameter about 24.4 in (620 mm). Part number toy255370.

IMPORTANT: Racing use only. Toyo states the Proxes R is not for highway 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.
