My tires are 245/45-17 F. and 285/40-17 rear. I think I calculated it at 26.97" diameter. Could be my speedo is a few mph off but I had my wife drive next to me before hooking up the speedo to verify rpm and speed. That's how I got the numbers. The rear end I did verify is a 4.10 Running a 650 DP on the car ideling at about 1000rpm if that tells you anything?


How did you come up with the tire size Bob?
