Westlake SU318 Tire Review & Rating

Built for today’s trucks and SUV’s, the Westlake SU318 is billed as a versatile and durable all-season tire that features a quiet and comfortable touring ride quality. It’s M+S rated tread design is built to provide increased traction and handling in all types of driving conditions such as dry roads, rainy wet roads, and light snow covered roads.

Westlake has included four wide circumferential grooves in the tread design that deliver enhanced grip, lateral traction and overall handling on wet road surfaces.

An advanced Silica Tech technology and sipes around the tread give the SU318 added handling when it comes to not rain soaked pavement, but on light snow covered roads as well.

Westlake hasn’t forgotten about ride comfort on the SU318 either. The tread design and steel bead wire helps eliminate most of the unwanted road noise and improves overall ride comfort, which is an area that we’ve heard other drivers mention in reviews.

The Westlake SU318 tire is available in over 30 different sizes that range from 15-20 inches and come with either a T, H or V-speed rating.


  • More than capable traction and handling on dry/wet/light snow roads
  • Quiet riding tire
  • Respectable tread wear
  • Budget-friendly price


  • Added road noise as tires wears down

Overall Thoughts

The all-season Westlake SU318 succeeds at what it was designed for… filling everyday driving needs in a variety of different weather conditions. It delivers very good traction and handling on dry or wet pavement, as well as on lighter amounts of snow. The ride is comfortable for the most part, although perhaps not on the level of models like the Michelin Defender LTX M/S, Yokohama YK-HTX and a few other tires.

A couple areas of concern would be a little added noise as the tires wears down, which is common for all-season tires, and the grip on ice and hard-packed snow. Traction falls off in rougher winter conditions since this is not a dedicated winter tire.

Overall, the SU318 offers performance that is not that far below what you’ll find on many premium brand tires in its class. We give it a middle of the class ranking. If you’re on a tight budget and needing a dependable basic all-season tire for your truck or SUV, this tire is not a bad option.

  1. The model’s groove pattern helps boost the hydroplaning resistance. Hydroplaning happens when the water and slush located on the rod surface cuts off the tire’s contact with the road surface.

  2. Are these Westlake tires 4 ply, 6ply, 8ply, 10 ply? I was told to Look for a 8 or 10ply reasonably priced everyday city tire for my 2006 Chevy suburban.
