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°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).

• Operating Temperature: 160°F to 220°F
