The advice I got from Brenspeed was to look at the tire revs. If they are within 20, you should be good to go. Mine was only off by maybe 3-5 so I didn't even bother.

Tire manufacturers revs data is usually way off. The only way to tell how a tire will work on your car with your rims is to measure the tire height (while mounted and installed on the car), multiply by 3.142 to get diameter. Then take 63360 (the number of inches in a mile) and divide it by the previously found tire diameter. The result will be revs per mile.
