Hey guys. Just figured I'd post some pics of my wheels installed after I used so many of your pictures to help me make my decision.

I bought these nearly new from a member on here. 305/55/20 Nitto Terra Grapplers on 20"x10" American Racing MT-700's (4.5" backspace).

I've very happy with the way they look, but even after a lot of modifications, they still rub pretty good.

Torsion bars are turned up two threads from the top of the adjustment screw. My truck sits dead level front and rear. The ride is still good. I would say my 285/75's on stock wheels rode better, but it's not too much different.

I spaced my front bumper out about 1" with washers. (You can see this in the underbody shot. Your looking at the front bumper bracket which I flipped onto the other side of the frame support and spaced out with a few metal washers). I still had to cut quite a bit off the painted front valence and fenderwell liner for them to clear. (One shot shows the front valence trimmed and the other the trimming on the driver's front wheelwell. Passenger's side looks basically the same).

The front tires are still rubbing on the body by the cab. I trimmed back the body basically as far as you can trim it back. I still have slight rubbing on both sides in a tight turn and any entrance into a driveway or other sloped surface while turning causes it to rub pretty good. Still haven't figured out how I'm going alleviate this yet. Maybe I'm going to have to do a leveling kit and some 1" blocks in the rear (to level it out).

The wheels and tires fit perfectly in the rear.

Anyway, I'm very happy with how it looks and will be very happy with how it drives once I get the tires to not rub.

Love the way the 10" wheels look, but the last ones I had rubbed also, so this time I went with 8". Your truck looks awesome with them on though!

get the cognito leveling kit with block in the back and you should be fine. It worked for me and my wheels have more backspacing.

looks kick ass love the stance but watch out for that little metal piece next to the nerf bar behind the plastic. i've had them cut into the tires at full crank goin up a grade.

that looks sick.
if i was to have a wheel with 5" bs same tires would i get more or less rubbing?

Westin - Thanks! I think that's my next step.

1lowdiesel - Thanks for the compliments. I tried to smooth that little metal piece down as much as possible but it has still lightly cut the edge of my tread. I'm having to be careful when I turn up driveways and stuff. Too bad GM didn't leave a little more room.

ray4224 - A 5" backspace would move your tires in more so the arc of your tire wouldn't be as much. Your steering lock-to-lock is the same, just when the wheel and tire bugs out more, it also swings farther forward and back when you turn. So to answer your question, a 5" backspace should provide less rubbing compared to a 4.5".
