Trail repairs: Re-seating the bead.

A common method for increasing traction off road is to air down (decrease air pressure in the tires). A common rule of thumb for radial tires is to roughly half it... If you run 30 psi on the road, go down to about 15 psi for off road. You might lose about 1" or so of ground clearance, but you will double your tire's contact patch.

One disadvantage of doing this is that it increases the likelyhood of loosing a bead (when the bead separates from the rim giving you zero psi instanty. This usually happens when there is a sideways stress on the tire (turning, slode slope, side winching, etc.).

If you try to re-inflate the tire, the air might be escaping faster than you can put it in.

Remove the wheel from the vehicle and lay it flat on the ground. Clean out any debris that you can see on the bead or rim. Get the 2" ratchet strap out of your toolbox and tighten it around the circumfrence of the tire at the center of the tread. This helps hold the bead of the tire next to the rim long enough for you to air up. Expect the bead to "pop" into place, perhaps twice if you separated both beads. Use no more than 50 psi for this. The large hammer on the sidewall trick (leaking around the bead thread) helps seating the bead too.

Good luck and happy trails.

I keep a tube of cheap grease in my rig works good for reseating the bead

that sounds a lot safer than the ligther fluid method
