- Variable sipe density - higher sipe density on inside tread and lower sipe density on outside tread - Snow claws - Slush grooves - Multi-wave sipes - Carries the Three-Peak Mountain Snowflake (3PMSF) symbol - For excellent traction on ice and snow and traction on wet and dry roads - Improves deep snow traction and increases block rigidity for better ice and wet traction - Evacuates slush for increased traction on slush and snow
