Designed to help full-sized pickups work hard on pavement, then work just as hard when roads are muddy, snowy, and rocky or when there are no roads at all. The Open Country M/T combines solid on-road performance with extra ground clearance, higher load-carrying capacity, and greater ability to go off-road. Truck enthusiasts know it for its long wear, low noise and aggressive tread pattern. An aggressive all-around light truck radial specifically designed for lifted pickup applications. The aggressive tread can crawl through any mess, while the smart lug placement and design provides precise, quiet driving on the street.



Best 4 street, snow, mud, rain & towing

I use the 37 tires on 18 inch rims on my 7 inch lifted platnuim tundra. ive offroaded all over southern cal. I bought a spare tire even though i was inform by other toyo onwers the tire never gets flat. quite is important becasue we drive all over and go from the street to the dirt all the time. I pull a horse box, dump trailer and boat with no problems. the tire looks amazing. im about to buy my third set of toyo becasue i put the miles on my truck. never been stuck.ive been in deep wet mudd and never had to use my winch to get my truck out.cant say that for others ive helped.

50K mile tire

Toyo Mt 37 13.50 18's I have them on a 2008 F250 Diesel Truck. I have 47k on them now, i expect to get another 10 K before its time to make tire swings. That is amazing, especially for a 9K pound truck. I regularly tow a dump trailer and 5th wheel. In excess of 24K pounds. I use them on the highway, dirt and mud. They are great tires. My brother has them in 20's, he has 60k on them. They are just about bald though. We will buy these again.

Can this fit on a 8" wide rim? Thanks.

Hello ARefaat, We suggest going no wider than a 12.50 wide tire on an 8" wide wheel. 13.50" wide require a 9" wide wheel minimum. Thank you.

Will this tire fit on a 2008 Jeep Wrangler JK four door with a 4.5" AEV lift and 18" wheels with 4.5" Backspacing? I want to make sure I will not have rubbing...

Asked by Forrest from Denver, CO on

Sir, with a 4.5" lift the largest tire you could run is a 35x12.5r. Thank you for your question.
