The Wrangler TrailRunner AT is Goodyear's On-/Off-Road All-Terrain light truck tire developed for pickup truck and sport utility vehicle drivers looking for traction in all conditions. The Wrangler TrailRunner AT is designed to combine long wear and durability with year-round capability on- and off-road in dry, wet and wintry conditions.Wrangler TrailRunner AT tires feature a chip- and tear-resistant tread compound molded into an aggressive, symmetric tread design with large interlocking tread blocks for added durability on- and off-road. Saw-tooth block edges and multi-angle sipes increase off-road and winter weather traction. The tread pattern has been optimized to promote even wear and enhance treadlife, in addition to minimizing noise from the aggressive features. Its internal structure includes twin steel belts with a spirally-wrapped nylon reinforcement on top of a two-ply polyester cord body to combine strength and durability with a quiet ride.LT-metric sized Wrangler TrailRunner AT tires featuring a 5-rib tread design (245mm and wider section widths) meet the industry's requirements for Severe Snow Service and are branded with the three peak three-peak mountain snowflake (3PMSF) symbol.Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.
