to my knowledge, the only problem this could cause, is if the tire machine
damages the bead.  you could develop a slow (or not so slow) leak.

that especially sucks when you don’t find out about it until you are hard in
a corner, and realize there is a bout 8lbs of pressure in the left front
tire  you tear the side wall apart, rip the tire completely off the rim,
wrap the tread around the spindle, shoot off the road, the rim digs into the
soft ground on the other side, you shoot back across the road to the other
side, and stop about 8 inches short of wiping out some grouchy old man’s
HEAVY duty wooden fence, and have to walk the next 2 miles to work because
you took the spare out because it was "unnecessary dead weight".

or so i’ve heard.
