Changed a lot of tires on cars, trucks, ATVs etc and for a home workshop that needs to be able to change ATV tires themselves this is AMAZING! Bought this bead breaker along with small tire changers from Ken Tools and let my 13 and 11 year olds change their own ATV tires. ATV shops in my area charge $40-$50 per tire just to remove/install ATV tires so it's already paid off. Good product! Although it's much faster with a percussion gun, you can also do it with a regular ratchet.
