I bought a stop-n-go plug kit from my dealer & the cheapest 12v air compressor I could find from Walmart. Before I had my last rear tire replaced, I drive a shingle nail into it, pulled it out, patched it with a plug and blew it up with the compressor. Drove it to work for 3 days (20 miles round trip). Didn't lose a pound. Worked for me. My $.02 worth.
