Anyone running 20" KMC Rockstars HELP!

user619582 · 08-19-2008, 09:50 AM

Trying to buy some KMC rockstars for my 2wd 2500 with a 2" leveling kit. I got 33x12.5x20 tires. Here is my problem, noone can seem to tell me what offset I need. I was told to get the 20x8.5 with -11 offset dont know how exactly they measure offset but once I order them they are my problem. Any help would be great.

No issues here, happy customer. I have 18's with I think 4.5" of backspacing (the only available if I'm not mistaken for the 18's) and they are out of the fenderwells pretty far. You can kinda get an idea from this, and if you'd like I could snap a few straight on shots for you.

Im a happy customer with 20 x 12 Black Rockstars with - 40 offset.They rub the back of the front fender right before full lock.No leveler or arms yet to push the axle forward.Though they stick out far far.There is a guy on here with a Mega Cab with 20 x 8.5 with 33 x 12.50 or 35 Toyo M/T and his truck looks pretty awesome without any rubbing with a leveler and he has a 4x4 I think.He will probably read this and post pics to help you out since he got the setup your looking for,though here are mine just to see what your looking at basically yet your's won't stick this far out.

I have never had any problems with my wheels, and I have had a few sets of KMC's. Mine are 20x10's, and I think there is only 1 back spacing for that size. Good luck to you, and hopefully you get it sorted out.
