Toyo Proxes R1R is 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 summer tires, these tires are not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice. It's also essential these tires be stored indoors at temperatures maintained above 15 degrees F. The Proxes R1R molds a high-grip, silica-reinforced tread compound into an 8/32" to 9/32" deep directional Arrowhead tread design featuring an extra wide footprint to blend handling and performance during spirited dry-road driving with traction in wet conditions. The leading edges of the arrowheads are tapered to stabilize center block movement to reduce the possibility of irregular wear. Multi-Width EVAC Channels improve water evacuation from the center of the tread design to help increase hydroplaning resistance, while their narrow widths at the shoulders increase block size to enhance steering response and maintain block stiffness during aggressive braking. The tire's internal structure features an advanced competition-inspired modified radial construction for driving hard through the corners and accelerating quickly onto the straight-aways. Twin high-tensile steel belts reinforced with spirally wrapped jointless cap and edge plies control the footprint size and shape. Jointless beads anchor the tires to the wheels while a high-modulus bead compound and slightly angled body plies work together to stabilize the sidewall.
