The need for removing the tire from the wheel (bead) and the subsequent installation occurs, usually when replacing tires on a new and suitable operating conditions, as well as for their injuries.
Before removing the bus from the rim, be sure to mark its position with respect to the wheel to follow when installing do not break balance. But before installing the tires need to check the status of the rim and all-wheel drive: Do not strain bus, cracks, burrs, sharp edges that can damage the gums.
Places of corrosion on steel wheels better time to clean up the shiny metal, primed and tint (using tubeless tires it is - a mandatory requirement).
If the board bus with difficulty separated from the rim to "soften" the compound inject the butt for 3-5 min slightly penetrant (WD-40, "Unisma" or something similar) - is facilitate the work. Remove the tubeless bus with the wheel can be difficult.
For high quality rubber and a smooth, flat mounting surface rim, as well as long-term operation, it firmly "stick" to metal. Even more difficult is again put on such a bus on the wheel.
When a regular car air pump or compressor household will be out until the ring side tires do not skip over the Hump wheel. For landing such a bus need a massive air supply professional compressor.
So for the repair of tubeless tires is better to apply to the specialized tire mounting workshop. If the damage is bus in a way you can install it in the proper-sized camera that is acceptable too, just to get to the tire changer shop.
