All-weather/all-terrain tread pattern provides superior traction in diverse conditions, from dry highways to snowy trails. A 3,195 lb load capacity handles heavy truck and hauling demands. Pinned for #16 (15mm) studs.M+S (Mud and Snow) and 3PMS (Three?Peak Mountain Snowflake) represent different levels of winter?weather tire certification.

• M+S tires use wider tread gaps and more aggressive patterns to improve traction in mud and light snow, offering basic winter capability.
• 3PMS tires meet a stricter, regulated standard and must pass tests proving strong performance in severe snow conditions. This certification guarantees measurable traction in harsh winter weather, unlike the self?certified M+S marking, which relies on no testing.

3PMS tires earn their certification by passing a standardized snow?traction test, typically the ASTM F1805 test. The tire is tested on packed snow and must deliver at least 10% better accelerative traction than a Standard Reference Test Tire (SRTT). Only tires that meet this performance threshold—verified through regulated testing—can display the 3?Peak Mountain Snowflake symbol.
