Although you might not expect your average human to be so
dimwitted, this has been going on for as long as I've been
around bicycles. And the surprised looks are just precious.

Huh! Does anyone know, is it supposed to be just the
exhaust temperature that causes this, or some chemical
reaction to the exhaust?

(I wouldn't have thought exhaust could get a rim that hot
unless the rim was within a very few inches of the tailpipe
- and I assume hitch racks don't hold rims that close to the
pipe - but then, I don't use hitch racks).

We still see tires charred by exhaust on bike racks.
