The Proxes RA1 is Toyo's Racetrack & Autocross Only tire developed for drivers looking for street-legal circuit tires that combine consistency, durability and competitive times. Proxes RA1 tires are designed to provide an uncommon advantage to cost-conscious competitors who demand quick lap times and long tire life from their racing tires.
While Proxes RA1 radials meet DOT requirements, they are not appropriate for highway use. Proxes RA1 radials are not recommended for driving in wet conditions when shaved or worn 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 RA1 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.
Toyo Tires recommends the following general set-up guidelines for the Proxes RA1:
-Operating Temperature: 160°F to 220°F
-Hot Inflation Pressures: High 30s to Low 40s (psi)
-Camber: -2.5° to -5.0°
