The Proxes RR is Toyo’s Racetrack & Autocross Only tire developed for driving enthusiasts who compete in road racing and track attack events where high levels of grip in dry conditions is required.

While Proxes RR radials meet DOT requirements, they are not appropriate for highway use. Proxes RR radials 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. And like all Racetrack & Autocross Only tires, Proxes RR radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It’s also essential these tires be stored indoors at temperatures maintained above 15 degrees F.

Proxes RR tires feature a high-grip tread compound 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 race-ready design eliminates the need for tire shaving, however Proxes RR 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 symmetric rayon casing construction to deliver predictable handling and consistent lap times throughout the tire’s life while reinforced sidewalls deliver enhanced steering response and cornering stability. A marking area integrated into the sidewall design allows racers to easily label and manage their tires.

Additionally, their symmetric tread design and internal construction allows them to be mounted on either side of the car (and later be mounted inside out to further extend their life).

Note: Effective 2/1/2014, the Proxes RR will become the spec tire for NASA American Iron, Camaro Mustang Challenge, Honda Challenge, Factory Five Challenge and 986 Spec classes for dry weather competition.

These classes will still be permitted to use the Proxes RA1 tire for the first two events of the 2014 season in each NASA region for dry weather competition and may use the Proxes RA1 at any time during the 2014 season for wet weather competition.

To assist competitors with the transition period, Toyo Tires is making a significant concession and allowing any Toyo Bucks issues from this point forward to be used toward the purchase of Proxes RR tires along with extending the expiration date on all Toyo Bucks until April 1, 2014.

Toyo Tires recommends the following general set-up guidelines for the Proxes RR:

  • Operating Temperature: 160°F to 220°F
  • Hot Inflation Pressures: 32 to 38 (psi)
  • Camber: -1° to -3°
  • Caster: As much positive as possible

NOTE: Please follow the specific mounting and rotation guidelines provided by Toyo for their Proxes RR tires as recommended in the link below.
