It took 2 years to find adapters for rims under 12. These adapters fit Mayflower tire changers and appear to fit multiple models. It took 20 minutes to set up my car and change my leg. You will need the included foot jewel or you will not be able to remove the smaller splint. Another problem is that the rim clamps close quickly and injury is very likely when aligning the rim, so use caution. Between assembly and disassembly times, it's best to make sure you have a few tires to remove and apply. I couldn't get the lawn mower tire off with a tiny rim, the rubber is too stiff, but other than that it worked great on the general purpose tires and golf cart wheels. Hope the photos help.
