Description

The Westlake SU318 H/T is an all-season highway tire for SUVs, crossovers and light trucks. Four wide circumferential grooves and shoulder channels clear water and slush from the tread, helping wet grip and keeping the ride calm and quiet.

A computer-optimized block layout reduces noise and vibration, while serrated siping adds bite in dry, wet and light winter conditions.

In the 255/55R18 size, this tire has a 109V load and speed rating with extra load (XL) construction. Specs include a 50 psi maximum inflation pressure and a UTQG rating of 500AA.
