Vehicular tires, mounted on wheel rims are more safely inflated, in a rugged box enclosing the entire tire-and-wheel-rim assembly using an, inflating line that penetrates through the wall of the box with a pressure, gauge visible from outside of box. Interlocks can be provided to help assure that the box must be closed before inflation can be started and that, the box cannot be opened for 3 to 10 minutes after inflation is completed. A window can be provided for visually inspecting the tire-and-wheel-rim assembly during or after inflation, and a deflation valve permits deflation if the inflation appears unsafe. The box can have welded-on reinforcements.
