A method and apparatus for seating the bead of a tubeless tire onto a rim of a wheel. Also included is a cartridge and a bead seater kit. The bead seater apparatus includes a barrel with a nozzle. The apparatus is further provided with a tab which is associated with the barrel. The tab forms part of a rim safety mechanism, which places the apparatus in a ready to fire position when the tab is pressed against the rim of a tire thus placing the nozzle in the proper orientation between the rim of the wheel and the bead of the tire. With the safety released, the trigger is free to be pulled, which causes a firing pin to hit the primer of the cartridge chambered in the firing chamber of the apparatus. The propellant is then ignited wherein the resulting gas is substantially instantaneously released through the barrel and out of the nozzle between the rim and the tire. This, in turn, causes the tire to be at least partially inflated resulting in the bead of the tire to engage against the rim of the wheel, thus seating the tire. The apparatus does not chamber standard ammunition since the cartridge is either substantially shorter than standard ammunition or uses a caliber than is not used with conventional firearms. The cartridge is preferably a center fired shot gun shell having a hull with a primer. The cartridge is filled with an ignitable propellant but does not have any projectiles. The kit includes the bead seater apparatus, and at least one cartridge, and a carrying case. In some embodiments, the case is a hard case.
