Westlake SL309 Tire Review & Rating

The Westlake SL309 offers drivers a combination of all-season traction and handling to go along with the strength to haul heavier loads. Built for all types of pickups, SUV’s and vans, the SL309 is ideally suited for those looking for a tire to handle the rigors of heavy-duty use.

An all-season Silica Tech tread compound is designed to increase year-round traction on dry or wet pavement, as well as lower the rolling resistance for added fuel economy.

The M+S rated tread is also siped for added grip on wet road surfaces. Four circumferential grooves and numerous lateral grooves effectively evacuate water and reduce the risk of hydroplaning. The sipes on the SL309 further add to traction on snow and ice, although we would like to see more grip in deeper snow and hard-packed ice.

Westlake uses variable pitch tread blocks around the tire to help in reducing unwanted road noise and improving all-around ride comfort. We’ve heard several reviews from other drivers that this model is more quiet than some of the bigger brand name tires.

Inside the tread are two steel belts that increase durability. Westlake has a wide range of 15-18 inch sizes available, and all LT tires feature a Load Range E rating.


  • Reliable dry/wet traction
  • Treadlife is better than average
  • Lower price for budget-minded drivers


  • Deep snow and ice traction could be better
  • Increased road noise as tire wears down

Overall Thoughts

It’s hard to walk away without being somewhat impressed by the all-around performance of the SL309. For delivery drivers, construction site vehicles and anyone else who needs a tougher all-season tire, this model holds up pretty well.

Our only real concern with this tire is its winter traction and braking. Like most every all-season tire, it can struggle with heavy deep snow, freezing rain and ice. Although it is M+S rated, you won’t mistake it for a winter tire.

That said, overall the Westlake SL309 is a reliable, well built and dependable tire that is also value-priced. While you could easily argue that it falls short of the performance you would find on similar tires from Cooper, Yokohama and other larger name brands, the SL309 is one of the better second-tier models.
