My Pro is lifted with Eibach's drop in springs for the factory Fox Shocks and running the factory Pro wheels. Hopefully someone with a similar set up can confirm this for me.


Even after reading their notes I'm not sure where my wheel specs fit in due to them being 17x7 with a +4mm offset, am I over thinking this?



Please Note: 32.5" and larger diameter tires need aftermarket wheels with less then factory wheel back space. Tire Size Calculator

LT285/70R17 (32.7" x 11.2") tire on 17 x 9 wheel, -12mm offset (4.50" backspace)
LT285/70R17 (32.7" x 11.2") tire on 17 x 8.5 wheel, -9mm offset (4.30" backspace)
LT285/70R17 (32.7" x 11.2") tire on 17 x 8.5 wheel, 0mm offset (4.75" backspace)
LT285/75R16 (32.8" x 11") tire on 16 x 9 wheel, -19mm offset (4.25" backspace)
LT255/85R16 (33.10" x 10") tire on 16 x 8 wheel, -12mm offset (4" backspace)
LT315/70R17 (34.4" x 12.4") tire on 17 x 9 wheel, -25mm offset (4.00" backspace)

Any tire that is 32.2" diameter and smaller there is no fitment problem.
