I have 31 10.50 BFG AT tires on my F150. I was looking for a 31 10.50 so I had a true full size spare, so I wouldn't have to worry about the limited slip differential. Well, because of all the good feedback I have been seeing about Tread Wright, I ordered their Warden AT. Its about half the price, since its on sale for 75 bucks right now.
