On-Road All-Terrain tires are for drivers who want a combination of focused on-road refinement, with some light off-road capability and all-season versatility, including traction in light snow. On-Road All-Terrain tires branded with the M+S and three-peak mountain snowflake (3PMSF) symbols are sometimes used as Original Equipment (O.E.) on light-duty 4WD trucks, crossovers and sport utility vehicles.
O.E. On-Road All-Terrain light truck tires are typically purchased as direct replacements for worn-out pairs/sets of the vehicle’s original tires. They can also be used for other vehicle applications in complete sets of four, or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. tires’ performance category and specifications.
Note: While non-winter tires featuring the 3PMSF 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.
