that math wont work....buy or borrow a portable GPS to see what your speed is.
As for MPG, I dont think there is going to be a direct conversion. Just calculate it the old fashioned way. Write down mileage at next fill up, then at the fillup after that, not how many miles you have driven since you filled up last and divide the number of gallons used to fill up by the miles you put on.
doh! how true you are. BUT with some additional math you could correct for distance driven knowing the circumference of old tires and new.that math wont work....
with the larger tires.... your "miles driven" will show less than you actually traveled do to the larger tires.. it will give yu the same number your dashboard is telling you doing it your way.
just was curious...not a big deal... thought maybe someone had a formula.
The circumference of your tire is (35/32) that of standard. Thus all linear functions of distance traveled, such as MPG and MPH, are calculated using the same ratio.
More precisely, the ratio is (New tire diameter)/(Standard tire diameter).

Or you could quit being cheap and buy a procal or flashcal :tomatoes:so then about 9.4%
32 x 9.4% = 3.008 + 32 = 35" tire
I guess that makes sense : /
Put your information in that link and you can easily compare to see the difference at 55mph.
