Tire Diameter
20" tires on a 2013 Ram 1500 have a 32.5 diameter 17" have a 31.7 diameter. What would be the apparent ratio or formula to arrive at such based on 3.55 gears.

Thanks. Ram claims 20's are optional, but of the many many I looked at none had 17's. Every salesman told me that they had never seen one either. I kept the 17's that I had on my 2012,mainly to maintain the gear ratio and because I thought the chrome 20's were just ugly.
