We bought this tire changer because we didn't want to have to buy an expensive piece of equipment AND upgrade our air compressor capacity. This tire changer was perfect! Our previous tire machine would only allow us to change up to 15" tires. The TC500M works great for all our needs. The tubular metal arm that rotates the deck and works the bead breaker could be better constructed (ours bent) but other than that the TC500M has been a welcome addition to our workshop. The price was great and the customer service was great too!
