I bought this hammer to bust tires on 17 inch rims. Light duty truck/car tires, I used a mixture of dish soap and water to lubricate the tire, hit it with a hammer about 6 times and the tire immediately popped off the bead. The hammer worked as usual. I have also used this hammer on Dayton 11r22.5, 11r24.5, 10.00x20 and Supersingle wheels. This has always been done. I highly recommend.
