I have a 2008 Suburban 2500 that used to be a border patrol truck. I am still getting to know the truck a bit. It was riding really rough and noticed that the front was riding higher than the rear. I assumed that the torsion bars were cranked, so I backed them off a bit and it now rides level. However, the tires now rub. They are 265/70r 18 (approximately 32.6"x10.4"). I am guessing the aftermarket rims might just have the wrong offset, maybe sticking too far out, but before I replace the rims, I should probably figure out what the max tire size for that vehicle should be. Does anyone have any idea what the max size tire should be for the 2500? I think the 2500 rides higher than the 1500, which means bigger tires. If those tires supposedly fit, then I know that either the rims have the wrong offset or the suspension has something funky going on, possibly from being a border patrol truck with a funky factory package...I think.
