Mounting and removing a tire from a wheel requires specialist equipment and knowledge. Tires have markings, generally referred to as the ‘GG ring’, and when installed this marking needs to be checked to make certain that the tire’s bead is seated correctly. Wheels are typically equipped with a rib that locks the tire’s bead in place, good fitment will ensure the best outcome in the event of rapid deflation and will ensure good wear and handling. Remember too that often tires are required to rotate in a set direction.
