as the title says i need wheels and tire combo

Lot's of people have 20's on a stock lift, 305/55R20's (33's) fit with a little rubbing and turning up the torsion bars and trimming. my dad runs 305/50R20's (32's) on his with a little trimming and a few turns on the torsion bars. Look in my garage for his truck.

Will 285/55R-20 fit without rubbing on a stock height 2500HD. Thanks in advance.

Those should fit with no problem, maybe a couple of turns on the torsion bars and trim the lower valance that's it. Those tires apear to be similar to 285/70R17 in size per BFG's website.
