Propane is liquid. (LP = Liquid Propane) (Now who is
the idiot?)
Liquid is a big difference from air.

Actually, it's not. A liquid is only a liquid because of
temperature
and pressure combination. IOW, you can take any gas,
compress it
enough, and it will become liquid.


However, that website that John
posted does prove I am wrong. I just wonder how much
weight is added
to a 15" tire when 32 lbs of air is added.

You can figure it out if you know the volume of the tire.

Do you mean the 32 pounds of air doesn't weigh 32 pounds?
