If you want to change tires by yourself, in your garage or at the hangar, you'll need 2 things: A BeadBuster and this Tire Lever Set (aka Tire Irons). The BeadBuster will break the bead loose from the rim, but you need a good set of tire irons to get the tires completely off of the rim. The unique curved shape of the large 15" lever makes removal easy with extra leverage, and it has the perfect shape for reaching over the lip of the rim to start the job. The shorter levers are perfect for working your way around the tire, and also have a curved tip on one end. These are quality levers, extremely rugged and well balanced, and they are a BeadBuster exclusive design. They are thicker and heavier than most tire irons you'll find elsewhere and are the perfect size for most tires.
