I'm running 33x12.5x20 Toyo MT tires on 20x10 Moto metal 951 with -18mm offset and 4.79" backspacing.
I have a pretty bad rub that doesn't allow me to get any more than a half turn in reverse.
Looking at the area where it rubs i may have to cut some of the body for it not to rub at all.
Anyone have some advice or opinion on this? I'm not sure if I should find a body shop to do this or not even bother and get an 18" rim with a smaller offset and backspacing.
My truck is a 2wd and has a 3" readylift leveling kit.

 

Had the same pronle with my 35's bc of the same backspacing. Took a cutting wheel on the airwrench and removed some of the liner and a little metal thats right behind it(you'll see). Also have to trim front valance. Did it same way. Thats probally what you are rubbing in reverse.

 

either grind it or get different wheels. 10" wide is part of the problem along with a -18 offset. positive offset wheels will be your friend. they can still be 20's, i wasnt for sure what you meant about 18" wheels

 

well I want the width.
I said 18" rims because the 18x9 moto metals have -12mm offset and 4.53" backspacing (or something close to that) instead of my -18mm offset and 4.79"
That'll give me about .5" less width and a little less rub, maybe enough to only have to cut fender plastic and no body.

I love the width.
