The Grabber APT is General's On-/Off-Road All-Terrain tire initially developed for Original Equipment use on the Nissan Titan, with additional sizes for the drivers of pickup trucks, Jeeps, crossovers and sport utility vehicles looking for a balanced blend of off-road capability and on-road civility. Designed to provide confident traction in all weather conditions, most sizes of the Grabber APT meet the tire industry's severe snow service standards and are branded with the three-peak mountain snowflake (3PMSF) symbol.Utilizing a robust, cut- and chip-resistant tread compound molded into a symmetric pattern, the Grabber APT's ComfortBalance™ Technology places an absorption layer under the tread to isolate the driver from imperfections in the road. Counter-angled shoulder grooves help to dissipate sound generated in the center of the tread for a quiet ride, and the flat tread profile and optimized pattern stiffness help evenly distribute pressure across the face of the tread to combat rapid and irregular wear. Full-depth sipes in the tread blocks create biting edges for grip on slippery surfaces and the staggered circumferential grooves, traction notches and alternating shoulder scoops aid traction on loose surfaces such as dirt or snow.Internal construction of the Grabber APT features General's DURAGEN construction to aid durability and provide a wide, flat footprint for even wear, braking performance and handling response. The two wide, ultra-high strength steel belts deliver resistance to punctures, in addition to supporting the tread for confident stability under heavy loads.NOTE: While most of the Grabber APT 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 the "Sizes" and "Specs" tabs. 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.
