Compare the revolutions per mile/kilometre for your old tyres, with the revolutions per mile/kilometre for your new tyres (these can be downloaded from the manufacturers website).

Heh, I actually tested my speedo yesterday. I was about 4-5mph off with worn 30" tires. I used a GPS with WAAS. So, when my speedo reads 75, I'm actually going 70. However, mine is an SR, so its supposed to have 31's.

The difference is the ratio of the old tire circumference/new tire circumference.
