I was wondering if 32" tires will fit on a stock 1998 Durango, and also if anyone has cranked up the torsion bars before, and how much you can crank them up.

 

32's will fit at stock height, however they will prolly rub. Your witdth will determine how bad they rub. 32 x 10.5 x 15 is the better size to go with stocke height or even a mild torsion lift.

do a serach on Torsion shackle lift, and you'll find your answer. I think if you even check on the next page, I've answered a question like this very recently.
