Check out the Interco Super Swamper special service tires at intercotire.com. I believe they make a 33x9.0x16 tire in the TSL design if you would like an agressive mud/semi-rock tire on your T4R. Not very wide, but the tire will not rub against the stock upper control arms of your vehicle. This would go well with stock rims and a 2.5" lift. I have had great performance out of these tires on my '84, but only about 25,000 miles.
