The Grabber AT2 is General Tire's On-/Off-Road All-Terrain light truck tire developed for pickup truck and sport utility vehicle drivers looking for exceptional traction over all terrains. The Grabber AT2 is designed to combine long wear and reliability with year-round competence on- and off-road in dry, wet and wintry conditions.The Grabber AT2 features a chip- and tear-resistant tread compound molded into an aggressive, symmetric self-cleaning tread design featuring five rows of independent tread blocks to blend on-road handling with off-road traction. The tread blocks feature multiple traction edges and sipes, as well as are molded to accept optional metallic studs to increase wintry weather traction. Tread block sizes and shapes have been computer-optimized to allow the aggressive tread pattern to remain relatively quiet and even wearing during on-road and highway driving. The tire's internal structure includes twin steel belts (some sizes reinforced with nylon) on top of a two-ply polyester cord body to combine strength and durability with a quiet ride.NOTE: While many of the Grabber AT2 On-/Off-Road All-Terrain tires meet industry severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol, some do not. Specific tires/sizes not meeting the industry's requirements are identified with a "Not Rated For Severe Snow" notation on Sizes & Prices, as well as on Specs. Grabber AT2 tires are designed to accept optional #13 metal studs to enhance ice traction.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.
