Edit: How are you guys comparing wheels/tire sizes? Are you converting diameters properly?

i wanna know that one 2.. its useless to compare RIM sizes.. its better to go of the wheel sizes (you know the WHOLE thing rim and tire..) cus that can be found relative easy and can be used to benchmark pixels by measuring from side to side of the wheel rather up to down (as the rubber distorts obviously arround the contact patch) cus even a few cm error on the wheel measurement which isnt much will translate to quite the few inches when scaled and comparing the whole car
roling diameter is found from from the aspect ratio so for eg a 225/40R18 has a aspect ratio of 40%
so the wheel height is 2 times 40% of 225mm (since there 2 sidewalls to the diameter) + 18" (but in mm)
so
(2*90)+457.2 = 637.2mm
and measuring across the wheel (ie from front to back rather than up and down) will get rid of the error due to flattening where the tire meets the ground
just a suggestion
