One common problem that off-roaders face is the hassle of a tire popping off the rim once you?ve aired your tire pressure down to tackle the tough trail. Not only can they be a pain to get back on, but it invariably leaves you in a precarious position. An old racers trick to prevent this is to take your rims and sand them down to bare metal where the tire seats to the rim. Then put chalk on that bare patch of metal, and then put on your tire. The chalk promotes rust and your tire will literally rust to the rim, making it far less prone to popping off at low pressure. The tire can still be easily removed with standard tire shop tools. A steel rim is the only requirement.
