Westlake SL309 275/65R18 light-truck tire
The Westlake SL309 is an all-season highway radial built for light trucks, pickups, SUVs and vans. Its 10-ply Load Range E construction supports heavy-duty loads up to the 123/120 load index. A Q speed rating allows sustained speeds up to 99 mph. The tire suits commercial light-truck duty as well as daily family use.
Check rim diameter and load needs before ordering
Confirm your wheels are 18 inches in diameter to match the 275/65R18 sizing. Verify the vehicle placard calls for Load Range E or a 10-ply rating so the 123/120 load index is appropriate. Ensure the 32.1 inch overall diameter clears suspension and bodywork without rubbing. The tire is not run-flat and requires a standard tube-type or tubeless rim.
Steel-belt radial with reinforced sidewalls
Twin high-tensile steel belts and a double polyester cord body resist punctures and aid off-road durability. Reinforced sidewalls add damage resistance on rough surfaces. Variable pitch tread blocks reduce road noise for a quieter cabin. Wide grooves and multi-sipe shoulders evacuate water and slush to limit hydroplaning. Rim is not included.
