Application June 29, 1943, Serial No. 492,684 _
9 Claims. (Cl. 144-288)
This invention relates to a tire handling stand
on which a wheel and tire may be rigidly sup
ported for the purpose of easily removing the tire
from the wheel and replacing it thereon with a
minimum of time and effort.
One object of the invention is to provide a
supporting stand, which will support the wheel
