Correct Odomoter readings

I'm about to pull the trigger on a Superchips for my 2010 wrangler. I've had 35's on it for basically it's entire life. I have roughly 28000 miles on it and I put the 35's on it around 8000 miles. I've done the computation to figure out my actual mileage compared to what the speedo is saying. But for you math geniuses, WHAT'S MY ACTUAL ODOMETER READING? or close to what it should be? Anybody have any know how on figuring this out?

Well, by "computation that you've done"... are you referring to speed variation?

What size tires did you have on it stock? Subtract the 8000 from the 28000, multiply by 1.xx (xx being the percentage difference between the tires. If a 10% larger tire than multiply by 1.1). Then add your 8000 to that number. This will give you the actual mileage.

~29,200 should be your actual mileage.


33 x pi = 103.62
35 x pi = 109.9

109.9 / 103.62 = 1.06

1.06 x 20,000 = 21,200

21,200 + 8,000 = 29,200

This is it. A guy on another forum was trying to use metric and it was throwin me for a loop. Too many back and forth conversions. Appreciate the help!
