The Proxes R1R is designed to be an ultra-high performance passenger car tyre that provides uncompromised performance for users that require a tyre with higher grip levels than most ultra-high performance tyres. It is developed for driving enthusiasts looking for capabilities beyond normal street tyre limitations. It utilizes a motor sport-inspired silica re-enforced tread compound, and a casing construction that features extra-wide steel belts and steel side plies for exceptional levels of wet and dry grip. The aggressive directional tread pattern prevents aquaplaning even at high speeds. Developed from Toyo’s years of gruelling on-track experience, Proxes R1R tyres are engineered to elevate performance in dry and wet conditions. However, like all Extreme Performance Summer tyres, these tyres are not intended to be serviced, stored nor driven in near- and below-freezing temperatures. Key Features and Benefits: Silica-reinforced, high-grip tread compound improves grip for better handling performance during high-spirited driving. Tapered centre block edge stabilizes centre block movement to decrease irregular wear and also helps to increase hydroplaning resistance. Advanced autocross-inspired casing with modified radial construction improves steering response and handling. Stability control slits provides resistance to irregular wear. Multi-width EVAC channels help to improve water evacuation and also widens the shoulder block area to enhance steering response. Unidirectional arrowhead tread design provides balanced performance between wet and dry conditions. Improves grip for better handling and performance during high-spirited driving. Shallow grooves and a unidirectional pattern achieve balanced performance between wet and dry conditions. Narrow width at the tyre edge widens the shoulder block area to enhance steering. The Toyo Proxes R1R provides exceptional handling and traction for high-spirited driving.
