Cooper Discoverer SRX All-Season Radial Tire -265/50R20 107T Tire Only 50,000 Mile Warranty Free 45 Day Road Test More Siping at Half-Worn - The RS3-G1 utilizes 3-D full-depth siping technology. This technology allows the sipes to go deep into the tread element, down to 2/32nds. Therefore, at half-worn the RS3-G1 has siping left to provide biting edges, keeping the performance consistent and enhancing the worn look of the tire. Ultra High Performance Construction - The sidewall is designed with a stiff rubber component inside the tire. Its purpose is to translate steering inputs from the rim to the road. The unique design of this bead filler component makes the RS3-G1 have a quick response providing feedback and confidence on the road. The rim protector extends beyond the rim flange and reduces the likelihood of rim damage that can occur if a curb is scuffed. A nylon overwrap combats centrifugal force under high-speed applications.
