Close, but....

Try ±¼" Diameter, not circumference.

Don't feel too bent over. As drive/traction/brake/stability systems become more and more complicated, tire dimensions become more critical. Until the OEMs begin writing fuzzy logic into these systems to allow for such problems, tire wear/damage replacements will continue to be a sore subject for vehicle owners. There is a lot of harrumphing going on in DC regarding these issues and tire safety. Next edict will likely be inclusion of tire pressure monitoring across the board. People are just too lazy/stupid (isn't it funny how lazy and stupid almost always go hand-in-hand?) to check their tire pressure/oil level/etc. and would rather spend $$$ on computers to tell them to do simple, periodic checks. How did we ever make it all these years without this stuff?
