Description

For SUVs, crossovers and light trucks that put comfort and wet traction first, the SU318 from Westlake is an all-season highway tire. Four wide circumferential grooves work with the shoulder ribs to drain water and slush quickly, while serrated siping bites into the road for grip in dry, wet and light winter conditions.

Computer-designed block layouts and optimized shoulder blocks help stability and cornering response, and a silica compound supports wet grip and lower rolling resistance for better efficiency.

In the 255/55R18 size, this tire has a 109V load and speed rating with extra load (XL) construction. Specs include 12/32-inch tread depth, a 51 psi maximum inflation pressure, a UTQG rating of 500AA and an overall diameter of about 29 inches.
