Westlake’s SU318 is an all-season tire that’s designed for use on CUVs and SUVs and features four wide grooves that drain water from the tread to enhance grip, traction, and handling during wet weather. Backed by a 50,000 mile limited manufacturer tread life warranty, the SU318 features a computer optimized design that lowers road noises and vibrations to create a quiet, comfortable ride for drivers and passengers plus serrated siping that bites into the road to increase grip in dry, wet, and light winter weather conditions.
