both have the same overall diameter (25.1 inch), so
knowing that, you can calculate the circumference:
25.1 x 3.14 = 78.814 inch.
And since there are 63360 inches in a mile, that would give you roughly 804 revolutions per mile.
Either that or my math is all wrong. :-)

If there is a difference, it is minute.
If you're asking cause you're potentially mixing and matching different tires models/brands.. don't do it.
As long as all 4 tires are the same brand and model and size, and have the same wear (tread depth matches), you're set to go.

slight differences in tire pressure will also change the rpm
but it's all not big enough to be a cause for concern.
Every time you turn, each tire travels a somewhat different distance, and that's OK, too.
