odometer calculation

[fdsinozich]

I changed the tire size and found the calculator for the difference in the speedometer. At 70 mph the speed is 73 mph, how do I calculate the difference in the odometer?
Thanks, Frank

If you odometer reads 70 miles, then you have gone 70 miles.

73 / 70 = 1.04286

Then, multiply what ever your odometer says, by 1.04286 (or where ever you round it to) and that will give you how far you actually went.


This is assuming your speedometer reads 70, and you are ACTUALLY going 73 (increased the tire size).
