    I am going to put the 38.5x14.50/15 TSL SXs on the Jimmy. I will be using 10 inch wide wheels to protect the beads, how much backspacing should I use?

    Stock backspacing is 3 5/8".....there are possible clearance problems with 4"......mostly just enough to know off the weights, and rub on your tie rod end(s)......I have 10" with 4" backspacing, and I have a clearance prob with the tie rod end on the passenger side......the rear are a non-issue.......try 'em on the front first..........JD

    Stuck?...Hell no..I still got some gas left..

    I have 4" of backspacing on my 10"s. They fit fine but there is only about 1/4" of clearance to the tie rod ends. Don't know if this will clear wheel weights as they are not balanced.

    I like the stance a lot though, I'm not big on tires sticking way out. Not very functional, gets hung up on tight trees and wears out bearings faster.

    What rims you have makes a diffeence too. Some are constructed differently.

    Be best to take the truck somewhere that has rims in stock so you can test fit before you buy.

    I was going to put the black rockcrawler wheels on the Jimmy that are currently on the burb, but I found out the the rears have more backspacing than the front:( So I cant rotate the tires because they hit the tire rode on the pass. side, and the rear is even narrower that it should be. So much for using those wheels. I will have to but new ones for the burb and the jimmy.

    Did you grind down the tie rod end or did you let it clearence itself?
