There are good compressors at Harbor freight and such that will run you a couple hundred bucks for a nice one. If you wheel on a regular basis i would think it would be a good investment. They just hook up to the battery terminals. you can drive for a little bit to get to a station with air and be ok. Of course the quicker the better. I only went down to 22 psi, if you go on down to 15 or so, just drive a little slower on curvy roads so not to roll the tire and break the bead. I had to drive about 40 minutes on the asphalt to get to air when I left Flagpole Knob, but Im not doing that on a regular basis neither.
