It will.....doesnt a 15x10 w 6.5 bs work out the same as a 15x9 bs? Looks like the math works to me. The inch difference is added to the backspace on the 10 right?

 

correct! Same as it would on a 10" wheel.....1" wider from hub face out...and 1" inboard. (comparing to an 8" w/5.5bs). Its hard to type out...I think you'll pick up what I'm saying (hope) lol

The problem is the 5.5 BS using a 275/60 is already tight on the fender lip. So any movement outward would be an issue.

The 15x8 and 15x9 having the same back spacing means the 15x9 is 1 more inch outward. Now the 15x9 and a 6.5 BS would be one more inch inward and same BS on the face. Technically a 15x9 and a 6.0 BS would be ideal. That would be =.5 and -.5 and keep the tire in the same place with more meat.

I can always move a wheel outward using a shim or spacer. The opposite direction... good luck. And once you mount a tire on a wheel.. you bought the farm

Hell the fix is minitub the car so I can make the wheels fit. Thats the Moby Dick fix... come hell or high water.. i'm gonna get that whale(make it fit)

 

A 15X10 w/ a 6.5 back space is what ya need. If the rim sticks out too far because of the disc brakes, just shorten the housing a half inch or so to pull the rims back in. No need to mini tub the car. A 15X10 inch rim w/ a 6.5 back space with a 28X10.5 M/T slick will fit as long as you roll the outer lip and get busy with a hammer on the inner fenderwell. Most of the 275 series tires out there measure just a little shorter than the slicks and don't seem to grow as much either.
