The Proxes T1R is Toyo's Ultra High Performance Summer tire developed for sports car, sporty coupe and high performance sedan drivers looking for comfort, performance and value. Designed to deliver in dry, wet and warm weather conditions, the Proxes T1R features an aggressive tread design that contributes to its competence. Like all Ultra High Performance Summer tires, Proxes T1R tires are not intended to be driven in near-freezing temperatures, through snow or on ice.Proxes T1R tires mold Toyo's Generation S silica-reinforced high-grip compound into a directional tread design that blends wet weather traction and dry road handling with noise comfort and ride quality. Shoulder blocks backed by circumferential ribs resist irregular wear while promoting dry road stability. Central v-shaped water evacuation grooves help pump water from under the footprint towards the shoulders to resist hydroplaning and increase wet traction.The tire's internal structure features twin high-tensile steel belts reinforced with spirally wrapped jointless cap and edge plies that control the footprint shape to promote high-speed durability and even wear.
