This revolutionary new device easily installs into all tubeless tires, while staying on the wheel. The Tire Plugging device 'drives' the tire plug into the hole, with a simple turning of the hex wrench. The tire plug expands under pressure to fill the punctured area. A firm pull on the stem with your pliers seats the mushroom head on the inner wall allowing no air to escape. This technology insures maximum reliability, while reducing your downtime in any situation.
