Shoot, that's easy.  You just get out your $3.99 tyre plug kit, pull the
nail and plug that sucka.  Get out your 12v air compressor and pump it
back up. (What???  You don't carry a tyre plug kit and compressor?  Then
why are you not on the freeway?)  12v compressor -- Offroading --  Don't
leave home without it! (Along with a fair amount of other items. Like a
tow strap, water, cell phone/CB etc.)
