Hell yeah they do. Get 'em from WalMart then do that extended warranty. Take your car and unbolt a lug, thread the front of the hand pump tee handle, lug it into the drive tire. If you were too dumb to anchor in J-Bolts to the concrete get you them there tap-cons. Tap them suckers in, bold up the hand pump, and hit the big 'ol go-button on your right foot. Lay the hammer down, bingo bammo, that hand pump is a compressor. And when it blows up you got spare parts and o rings and stuff. It can't go wrong. There's no point to waste money on a real compressor if you can just strap this stuff up to a jacked up car tire and make 'em both work for you! Take that warranty suckers! WOOOOOOO!
