If your Jeep has really wide wheels or very narrow tires, you may need a ratchet strap around the circumference of the tire to help push the bead bundles out towards the wheel lip. The strap can be very dangerous. If you must use one, stand back and only leave it on long enough to get a couple of psi in the tire. As you add air the tire grows in diameter and pushes with lots of force against the ratchet strap. Eventually, the strap can break. Those hooks and the ratcheting mechanisms can kill you if the strap breaks and either one hits you.
