I've heard the anti-car bicycle folks using brake dust pollution as yet another reason that cars should be outlawed.

On the tire shop topic, a few years back I gave my neighbor some snow tires I had no use for. The tires were 215/55R16 and the OEM tire size for his car was 205/55R16, but when you measured the circumference of both tires they were almost exactly the same. Width was very close as well.

The first tire shop he went to refused to mount the tires for him because the size on the sidewall was different than the OEM size for the car. Next shop he went to mounted and balanced them without an issue. Go figure. They fit and worked perfectly on the car, and he got a few winters out of them.

Man, I miss the days when people weren't so crazy. Sure was a better time to live in.
