Pretty tough to scavenge much without some basic tools. At least a wrench, a screwdriver, a knife, and a pair or two of pliers would sure be helpful.

Since I EDC at least a knife, I'm going to assume that I've got a knife, a tire iron, and a jack.

So, that nice spare in the back, it's probably the easiest to get to. Pull that sucker out, deflate it with a stab, then cut it up into strips. Makes a nice fire starter and more importantly it can be used to produce some nice black smoke, the kind that draws attention.
