Evolution man, I recall a few years ago, my boss backed into the shop with one of those red bead breakers on the pallet and 4 stubborn tires to his quad. It took us 4 hours to change the tires and we had to get pretty innovative. We still have it, but I usually just take my wheels to a local tire shop and they do it for free. But dammit that BB handheld looks effective. It will be In my inventory soon.
