The Proxes R is Toyo's Racetrack & Autocross Only tire developed for enthusiast drivers competing in track attack and road racing events where the demand for the utmost grip in dry conditions is a requirement.

Proxes R tires feature a next-generation tread compound formulated to create maximum grip molded into a semi-slick tread design including just two 4/32" deep symmetric circumferential tread grooves and multiple wear inspection holes in the slick areas. This symmetric tread design allows them to be mounted on either side of the car, and later be mounted inside out to further extend their life. This race-ready design eliminates the need for tire shaving, however Proxes R tires will benefit from heat cycling before competition to enhance wear and provide more consistent performance, as well as scuff-in during their first laps.

The tire's internal structure features a dual-layered polyester casing with twin steel belt construction to deliver predictable handling and consistent lap times throughout the tire's life. A high turn-up reinforcement in the sidewalls adds additional strength and immediacy to steering response and cornering stability.

While Proxes R tires meet DOT requirements, they are not appropriate for highway use. Proxes R tires are not recommended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. Like all Racetrack & Autocross Only tires, Proxes R are not intended to be driven in near-freezing temperatures, through snow or on ice. It's essential these tires be stored indoors at temperatures maintained above 15°F.

CAUTION! The rubber compounds used in this tire have unique properties that, when compared to other tires, can cause them to lose some of their flexibility when used or handled in conditions below 15°F (-9°C). This loss in flexibility can lead to potential cracking and other damage to the tire.

TO MINIMIZE THE CHANCES OF THIS HAPPENING, CONSUMERS AND INSTALLERS ARE ADVISED TO FOLLOW THESE INSTRUCTIONS:

  1. Do not move or operate the car with these tires in conditions below 15°F (-9°C). ALWAYS INSPECT FOR SIGNS OF CRACKING! NEVER USE TIRES THAT HAVE CRACKED!
  2. Avoid moving these tires in conditions below 15°F (-9°C).
  3. Before mounting or dismounting, store these tires for at least 24 hours in a temperature-controlled environment of 68°F (20°C) or warmer, and ALWAYS INSPECT FOR SIGNS OF CRACKING! NEVER USE TIRES THAT HAVE CRACKED!
  4. Remove these tires from the vehicle and deflate to half the normal air pressure during prolonged periods of non-use or storage.
