Westlake SL309 215/85R16 115/112Q E 10 Ply Tire

Westlake SL309 Light Truck Tire

The Westlake SL309 is an all-season highway terrain tyre built for light trucks, vans and SUVs that carry heavy loads daily. It carries a load index of 115/112 and a 10-ply load range E rating for maximum durability. The Q speed rating allows sustained speeds up to 99 mph on motorways. This tyre fits 16-inch rims with a 215/85R16 size designation.

Twin Steel Belt Construction

Internal structure uses twin high-tensile steel belts and a double polyester cord body with reinforced sidewalls to resist punctures and cuts. The 30.4-inch overall diameter and 85 aspect ratio provide a stable footprint for towing and payload work. Variable pitch tread sequencing reduces road noise for a quieter cabin on long hauls. Wide circumferential grooves channel water and slush away to lower hydroplaning risk.

Replaces Worn Highway Tyres

Drivers replacing original-equipment highway tyres on work trucks gain the 40,000-mile treadwear warranty and all-season siping for wet and winter grip. The upgrade makes sense when current tyres show sidewall damage, uneven wear or loss of wet traction under load. Buyers who need dedicated mud-terrain traction or run-flat capability should look elsewhere.
