Ideally all tubeless tires should be repaired from the inside/out. In case you don't already know, most, if not all motorcycle, scooter, and ATV dealers will not repair your damaged tire. So if you want to be self-sufficient on the road or in the wilderness, you need the Stop & Go - Tubeless Puncture Pilot. This kit allows you to make an on the wheel repair to your tubeless tire and re-inflate it on the spot. It includes the award winning Pocket Tire Plugger with its (15) mushroom shaped rubber plugs and the very compact Min-Air Compressor. This all fits into a durable zippered canvas case that measure only 7" x 4" x 3" and weighs only 1.7 lbs. The mushroom plugs measure 5/16" diameter shaft x 3/4" in length. They work on all tubeless tires while the Mini-Air Compressors are intended for use on motorcycles, scooters, mowers, small tractors, golf cars, and ATV's. Some other features include: 12 Volt Compressor unit with built in Gauge & LED Light, 66" Power Cord that fits Battery Tender connectors, 12" alligator extension clips & 36" extenstion lighter adapter, 4" tire valve hose with sports needle & inflatable adapter.
