The Proxes R1R is Toyo's Extreme Performance Summer tire developed for driving enthusiasts looking for capabilities beyond normal street tire limitations. Developed from Toyo's years of grueling on-track experience, Proxes R1R tires are engineered to elevate performance in dry and wet conditions. However, like all Extreme Performance Summer tires, these tires are not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
