If your rim now needs a 1.25 spacer, then a rim with that additional offset would eliminate the need for the spacer.So just to confirm, I'm looking for something with -1.25" offset if I want the same effect as a 1.25" wheel spacer?
I want to see your 8 foot wide rims!You need the wheel before deciding on spacers.
An 8' wide rim with 4" backspacing has zero offset. The hub mounting surface is in the middle of the rim.
Move the mounting point in or out and you have more or less backspacing, and then a positive or negative offset.
What are trying to do with your rim and tire setup?
Agreed.I ran 285/75/16s with 4.5" backspacing, no problems. That was with coilovers.I'm running 285 75 16's on 16x8 with 4" backspacing, tires have never made contact with the uca's. Stock backspacing is 4.5", so 4" bs s only .5" farther out. 3.25" bs would be the same as stock rims with 1.25" spacers. That much bs isn't needed and I would guess it would actually cause rubbing issues elsewhere.
