Acme Automotive introduces a new innovative 3-in-1 tool for tire and auto centers, service stations and dealerships. The Combo Tire Deflation/Inflation Tool removes the core while still having the chuck engaged to the valve stem. The full bore allows the tire to deflate, and the new tire to inflate quickly, all while the valve core is captured in the body of the tool. Simply screw the core back onto the stem when inflation is completed.
