I bought this 20-20- Coats tire machine 2 years ago and just never bought a biger comperssor. With my 1/2 hp. 15 gal. comperssor I had to help it by hand to brake the tire off. It has a 5 ft by 4 ft. metal base so you can move it around the shop. Has all the tools with it. . Thanks. ph. 785-483-9495.
