Les Schwab is generally over priced, and generally you end up with non-name brand tires. They are supposed to pride themselves on service, but they broke more things on my truck than any other shop. They broke wheel studs on multiple occasions from over-tightening, and I usually had to wait 45+ minutes for tire rotations.
I had a set of the mud terrain sxt in 31x10.50s. They were "okay". I think I had to have holes patched 2-3 times in them. Mud packed in them real tight, they were "okay" in snow.
Go to somewhere like discount tire, look at Cooper STT mud terrains. It is a much better tire all around, works great in mud and snow, much stronger tire and better sidewall. Also look at BFG KM2s. Both of those will be great tires and probably close to the same price as schwabs.
