Always interesting to see what others have come up with - I know there are lots of threads like this, but there's always new members and new ideas. Here's one for flat tires: We keep a 10-15 air tank on the truck/trailer for flats. This is always a good idea but sometimes a couple of flats in a day or a large tire that needs a lot of air can deplete all the air you've got stored. Instead of a trip to the shop or local gas station, I purchased a little air compressor (about $10) that plugs into the truck lighter/accessories outlet. We use this to fill the tank back -up to 120lbs or so (the compressor doesn't have enough psi/volume to bead tires). It works great and saves a lot of time. Even if someone forgot to refill the air at the shop, we've always got air. Another quick tip: Tire beading straps run about $30 in catalogs. I've found that with a liitle modification, the tie-down/ratcheting straps you get at the local auto store work just as good. All you need to do is make a loop and hook so that you can cinch the strap (back around into itself) around the tire. It beads a tire like a charm - never a second try needed - and it's a lot cheaper that the beading strap advertised in supplier catalogs. OK let's hear yours.
