My dad and i have been making a mud bogging truck for a while and recently we realized we needed a different frame. so he bought a 85 chevy pickup and it just so happened to have a brand new set of 31s on it. So we put them on my truck and it made a big difference. my truck has a meaner look to it now.
heres a close up of the tire. Its called the firestone wilderness at III, it is very similar to the bfg at. i even got a full-size spare out of the deal. when we took my old tire off the rim it had a bunch of water it it, i have no idea how it managed to get in there but it did.
