Best mud tire for the price.
This is a great looking tire. Unlike some other 35" mud terrains, these measure in true to size. They ride a bit rougher than stock rubber, but so does every other 10-ply tire which is your only choice in this size. I've run the Toyo M/T's before and I would say these are pretty much identical in terms of wear and ride quality. The only other tire I would consider would be a Nitto. They are more money, but supposedly a bit better according to most off-road shops I've spoken to. The attached images show these in a 35x12.50R22 on my 2015 F150 Platinum with a 6" BDS lift. I'm running a 22x10 wheel. You can see the difference compared to the factory tires.
