Looking at some 15x7 inch rims... which is the best offset for an xB... 28 or 37? I'd like to run 205/50/15s and avoid spacers/rubbing.

Thanks!

28 would be better than the 37.

28 is best but not ideal... 10-20 offset are what most people recommend for flushness.

Just don't want any rubbing... currently dropped on DF210s...

You won't rub with either.
The fronts would be decent, but I'd toss a spacer in the rear for 28.

Those aren't going to sit super flush, but it's all what you're looking for. If you don't want to worry about rubbing, the 28 is fine.

im on 15x7" rims with a 38offset thats the factory offset. the lower you go the more they stickout

I agree with everyone. Go with 28 you won't have a problem.

I suggest using the 37s in front and the 28s out back. Then you won't need rear spacers to even them out. Plus the staggered wheels will look great.
