Toyo Proxes ST III - 275/50R21 113V XL

The Toyo Proxes ST III is a street/sport all-season tire for light trucks, SUVs and crossovers; Toyo's fitment examples include the BMW X3, Cadillac Escalade, Chevrolet Tahoe, Infiniti QX60, Lexus LX and Range Rover Sport. It combines a silica-based tread compound with a wider tread and a directional all-season pattern.

Grooves cut into the pattern are there to move water out of the contact patch. Directional shoulder blocks are meant to steady the blocks under braking and keep noise down, multi-wave sipes are designed to reduce irregular wear and add light-snow traction, and arrowhead tapers stiffen the blocks for straight-line stability. Toyo backs the tire with a 40,000-mile treadwear warranty (rear tires on staggered fitments are covered for 50% of the stated mileage).
