Now available from Toyo Tires as an extension of its flagship Open Country H/T tire is the all-season, high-mileage Open Country H/T with Tuff Duty. The new tire was optimized for heavy-duty diesel pickup trucks used to tow trailers and haul heavy loads, and supplies extra life and increased wear thanks to its new Tuff Duty three-belt construction, decreased tread void, and deeper tread depth.

The new three-belt construction helps reinforce and stabilize the tire's internal construction, while decreased tread void equates to more evenly distributed contact with the road. Tread depth is available at up to 17/32 in., meaning more rubber to the road before it's time for replacement.

The new Open Country H/T with Tuff Duty is available in five sizes, with one 17-in. and four 16-in. sizes available for Chevy, Dodge, and Ford 3/4- and 1-ton heavy-duty trucks. A Tuff Duty mark stamped on the sidewall separates the high-mileage tire from standard Open Country H/T tires.

Available sizes are as follows:

  • LT235/85R16 120/116Q E/10 -- 16/32-in.
  • LT245/75R16 120/116R E/10 -- 16/32 in.
  • LT265/75R16 123/120Q E/10 -- 16/32 in.
  • LT285/75R16 126/123Q E/10 -- 17/32 in.
  • LT265/70R17 121/118R E/10 -- 16/32 in.
