I saw only one 14" tire at either place, or Highland Hardware. Do you
remember what the differences you saw were? Good advice to check
width. I measured roughly 1", but it might well be 7/8", per one of
these catalogs. I think all these _wheels_ have a crown, and the tires
are flat until being stretched over the crowned wheel.

Nah, all I remember was that there was a different one for Delta than
for the imports. Don't know why.
