I have a "Portable Viair Air Compressor" for sale. The Air Compressor is a larger portable compressor kit that can inflate up to a 35-inch tire (but I've inflated my 37's) from 0 to 30 PSI in less than 5 minutes. The Air Compressor is used and approved of by off road enthusiasts worldwide and can save you when you're miles from home. I'm selling it for $150.00.
