Sorry if this has been asked but I didnt see anything in search. I want to know if you can run 33 x 12.5 on 16 x 10 on a 2500hd buy cranking the torsion bars without rubbing or do you need green keys? Thanks....

I'm not an expert, but I think you would have to do some cutting to the fender to make those fit. I am running a 16x8 rim with 285s on them and they rub a little. Of course I don't have my torsion bars cranked yet. I know there are a few members that run 315s on stock rims with torsion bars cranked all the way and blocks in the rear. You will probably need at least 4" of lift for that combo.

For a while I was running 33 X 13.5's on 16X10's. But I also had 4" lift. I'm thinkn you'd probably rub a wee bit more than the 285's as they are only 11.22" wide.

Do you have pics of your combo?
