I'm running 225/50/15 tires on my alero.

According to miata.net tire calculator. which I calculated our stock tire size (225/50/16) to 225/50/15, the diameter is 23.9 inches while the stock tire size is 24.9. So in summary it says "speedometer reading with non-stock tire is 4.0% too fast, when your speedo reads 60 mph you're actually travelling 57.6 mph"

Also with a smaller tire, your odometer will go up faster, more wear and tear on your transmission etc. but who cares? At least your gear ratios will be different lol.

I will try to post up a picture of my alero with the 225/50/15 tires, but my car isn't lowered, but you will get the idea.
