If you do a search, you'll come across LOTS of info on tires. There are as many opinions as there are Forum members. I think Section525 has pics of his ride with 31s in his sig. As for the tires, my bother-in-law has been thru two sets of BFG A-T T/As on his 4Runner and cannot say enough good things about them. He prefers them over the Bridgestones that came stock and well as the 'stones on my sister's new 4Runner. They live in Colorado but have stayed on-road for the most part. I think he got about 60K miles on each set of the BFGs.
I plan to buy these tires as well, once Uncle Sam kicks my refund back.
