15x9 wheels

Anyone running 15x9 wheels wondering what backspacing works best.

I run 15x8 all around but in rear with 1" spacers for an effective 9" stance in back - 4.5" bs all around and plenty of rear clearance in particular - 4" BS up front might work for a 9" wheel to maintain chassis clearance but I assume others will respond in further confirmation

Cool that helps me thanks, thinking the 9’s in the back and 7 or 8’s up front.

Main reason I didn't stagger actual wheel sizes was to maintain full rotation ability instead of running 2 different size tires - this way I still get the stance but only have to carry 1 spare. Running 8's with 4.5" bs up front will leave you good chassis clearance and let you run up to a 245 series tire comfortably - in the back you can comfortably run a 255 series tire on 8's if you wanted.

some people have run up to 275 series out back on 8's but to me that's potentially tempting fate.
