Our take on the Toyo Open Country M/T 37x12.50R20 All Season Mud Terrain Tire with Load Range E

The Toyo Open Country M/T is a mud-terrain tire built for trucks and 4x4s that spend real time in dirt, rock and mud. In this 37x12.50R20 size it carries a 10-ply Load Range E rating, a 126 load index (3,750 lb at 65 PSI) and a Q speed rating, so it is aimed at heavy-duty rigs rather than daily commuters. Its 21/32 inch tread depth and aggressive, self-cleaning blocks give strong off-road grip, but rivals like the BFGoodrich KM3 and Goodyear Wrangler MT/R are quieter and better on wet pavement. Owners praise its toughness and mud traction and accept the road noise and fast wear that come with the category.
