tires rims and backspacing woes

[wyk3d]

I had a set of 275/60 nittos mounted on my rims. Turns out they have 4.5bs. This is a problem as the wheels wont even turn on jack stands without rubbing. My question is this, will 3.5bs fix the problem? Is there a way to be SURE of the right size? I dont wanna buy another set of rims and have them not work either. Frame notching is not an option and i dont wanna put spacers on either. Thanks for any info.

3 3/8 backspacing is too much. You want 3.5-4" of backspacing. I have 3 3/8 10" convo pros with 28" tall tires... 275's. They stick out a little, and would work perfect (no fender lip curl, no air bags) if it was 4" of backspacing.

3 3/8 backspacing is too much WRONG.......

3 3/8 backspacing will work PREFECT.......

I JUST PUT on 15X 8.5 3 3/8 backspacing With 28 x 10.5 slick, fit like a glove,

they look big, but no rubbing,
