I was under the impression that most 15" wheels would require some grinding and/or spacers to clear the calipers. I was pleasantly surprised to find that the 15x5.5 (3.5 BS) fit fine on the front. The rear rims 15x10 (6.5 BS) haven't arrived yet. I trial fit the front rims on the rear and, while the BS of the 15x5.5's do not extend over the full width of the rear calipers, it looks like the 15x10's should clear. I am going to mount 205/75-15's on the front and 305/50-15's on the back. This will be my 24/7 street setup. Tires came in today as well as the front wheels. I'm a bit concerned about the rears (11" tread width) clearing the fender wells. I measured it before ordering and it looks to be a close fit. If there's no rubbing on the street, then I may consider getting BFG DR 325/50-15's and another set of 15x10 Warriors when my 16" DR's wear out.

 

15x10/6.5 backspace will stick out a bit. Might work without grinding.

I run 15x10/7.5 backspace Pro Stars and they fit great. I think that 15x10/7.25 backspace would work well too.

I am getting a set of used 15x10/7.0 backspace Centerline rims to experiment with...

 

Update: The 15x10's arrived yesterday and did required some minor grinding on the inner portion of the caliper. Maybe about a 1/16th of an inch had to be removed. The 6.5 backspacing makes the tires stick out a bit, the same amount as a set of 17x11's with 7.5 backspacing. No rubbing at all with the 305/50's. The 305's give much better traction than the crappy RSA OEM tires. However, 205/75's in the front reduced the steering quickness and the braking grip. I like the skinny/fatty look though.

 

Does anyone have pics on where to grind the calipers???
