    Default Need an expert/ wheel backspacing and offset

    Here is the situation: I just put on a 2.5 suspension and 1 in body lift on my TJ. I have 31 in tires on my 15 x8 Cragar soft 8 steelies. I just purchased 33 12.5 15 Maxxis Bighorn MT tires. I had the shop mount one of the 33's on my Cragars for a test. It hit the lower control arm when the wheel was turned all the way to the left. So I had to put the 31 back on.

    So...... Here are my options. I can buy aluminum wheel spacer adapters for around 200 bucks or buy new wheels with the proper backspacing for close to the same price. I am thinking of going with new wheels so I can have a full set of 31's for backups if I need them. Does anyone know if there are wheels that I dont need spacers for my 33's? If there are what is the backspacing on them. Or do I have to get spacers? Would a 1.25 in spacer be enough? I would appreciate the input and like to find out what everyone is running. I know a lot of you are running 33 12.5's. Thanks!

    I was running 33x10.50 on 15x8 wheels with 4.5 in BS. The spare was on a 15x8 wheel with 4 in BS. I didn't have any issues.

    I picked up a set of 33x12.50s on 15x9 wheels with 3.75 in BS. It seems to be a perfect fit. No rubbing It doesn't matter too much if it is 15x8 or 15x9, 33x12.50s and 35x12.50s generally have no issues running with 3.75 in BS.

    Hope this helps.

    I agree with the 3.75" back spacing.

    I myself would also go with new wheels instead of spacers. That way you either have a spare set of rollers, or can sell the set of 31's to recoup some cash.

    I also prefer correct wheels to spacers, but that's a personal preferance, I know guys running the 1.25'' spacers w/no problems.

    The wheel width is up to you also, a 12.5 will fit on 8", 9" or 10" wide wheels. (I prefer 8" myself, but I air down to 7-8psi)

    You're gonna love the MAXXIS BigHorns!! Great wheeling tire, and good on the road!

    Good luck!!

    Thanks for the help guys. I think I have decided on a new set of wheels instead of backspacing. Those Maxxis look mean as hell and I cant wait to get them on my Jeep!

    erm, before you get radical and spend cash. did they hit all the way right too?
    I ask because I had this problem with my 2.5" ome lift, hit the CA on full left.

    reason- the lift was just enough to shift the axle 1/2" off center making it hit the CA on full left. one washer under the lock prevents this till you can get the right trac bar

    I think you can adjust your turn stops to help immediatley. I would stay away from 10inch rims and go with 8 inch wides if you like to air down.

    Hey Forma..
    Did you get those tires at Western Auto?
    Reason I'm asking soon will be buying tires for my JK.
    Need to find an agressive tire but soft at the same time, So it can float
    over sand (Hard tires sink like bricks in sand).
    As you know here in the desert we have Sand/Mud/Rocks/Snow and Ice.
    Hard to find soft All Terrain Tires.(Affordably)

    Later Dude.

    go for black steelies at least most 3.75" BS

    remember less BS mean wheel sticks out further = less chance of rubbing
    more backspace means wheel is tighter into the body but = more chance of rubbing

    3.5-3.75 is about the norm on 33's with a TJ
