The Tusk Portable Tire Changer is a great, easy way to change tires in the shop or at the track. This tire changer will work with all rim sizes 14 inch and bigger; dirt or street tires. One of the nicest features about this tire changer is the bead breaker; it has several different adjustments for different size tires to ensure good leverage to pop the bead. The changer also has an axle stud that securely holds the wheel in place on top of the rubber coated rim stabilizer that prevents scratching the spokes. Another great feature is the gap in the ring and the lower tab below; this is used to pry on the rim lock to make removal simple. With its compact design, it is perfect for the shop, trailer, or even trackside. -Handy rim lock gap to pry on when you get a stubborn rim lock. -Durable steel construction with black powder-coating.
