Re: Need wheel help
On the rear a 5.5in backspace on a 10in wide rim puts the wheel almost dead center. Not sure about the front but I've read that 20x8 with 5.25in backspace is perfect.

Re: Need wheel help
Back space is the distance from the mounting surface of the rim to the outetmost lip of the backside of the rim. Does that make sence?

Re: Need wheel help
Not exactly. Example; A 10in wide rim with 5.5in of backspace has 5.5in of rim on the backside and 4.5in of rim on the frontside.

Re: Need wheel help

Re: Need wheel help
I'm guessing your truck is 77c10 right? What wheel and tire set up do you want and is it lowered or not?

Re: Need wheel help
From what I've been hearing 18s are getting hard to find wide enough tires for, but I could be wrong.
