Why won't my new tires hold air?

[grundlegrabber]

Most common problems with atv tires are bead leaks. Sometimes hard to detect since they leak very slow, often caused by a minor ding or even a deep scratch in the seating area of the rim. Bead sealer is available at most auto parts stores. Break the beads down, coat the seating area on the rim with the sealer, install new valve stems. I use either the pull thru brass stems (made for high pressure applications but they work great in my atv rims), or the bolt in chrome stems, which I get from a friend of mine that works in a commercial tire garage. Your average automotive shop probably won't want to deal with your tires, best bet is to find a place that does commercial truck and equipment tires, or tractor tires. However, any shop that has the commonly used "rim clamp" type tire machine can break the beads and install new stems. The "fix a flat" type sealer is the lazy man's way of dealing with bead leaks. While it usually does stop the leak, it makes an absolute mess of the inside of the tire. Tubes will work, but they are a pain in the ass every time you get a flat. Can't plug them out on the trail. The tire also loses some of its handling characteristics when tubes are installed. I hate tubes and won't ever use them in my tires. There you have it, from a self proclaimed expert in atv tires.

The other day I sealed a Blackwater by using rubber cement on the bead, (it's called universal cement, you use it for tire patches and plugs). I didnt even break the bead, pulled the tire down with my knee, applied some of the cement between the bead and wheel, used a hairdryer to help the cement dry, and pumped the tire up in small intervals while using the hairdryer, it seems to have worked good.
