It may not be soon enough, but I will measure mine soon after I get my JL(20-24th)
I already have wheels/tires en route, as soon as I get the stock wheels off if they don't have markings I will do my best to measure it.
17x9" KMC Machete Beadlocks & 37x13.50 Cooper STT Pro. They won't be going on until I have a suspension sorted out, but I will put it on the lift and "simulate" a 2-3" lift just to test fit them. I may end up just going with a budget spacer lift until the better options become available(I see coilovers sometime in my future.)
