I think we need to build a wheel database for the conversion...
I am running the XRAY +0.75 in the front with AKA EVO TLR 22-4 wheels and have a track width of ~245mm when subtracting the thickness of the tire side walls. With the XRAY +1.5 in the rear and AKA EVO rear wheels (subtracting side walls), I also have a track width of 245MM. Ride height at 22mm.
