Recently I had a flat tire which cost me $405 to replace it. I had to move the car with flat tire on to the flat bed tow truck and back it down so it may damage more to the tire. I feel that if I have had to tire inflator / Air Compressor that at least with the slow leak I can use it to add some air in the tire avoiding running flat. Any recommend for portable tire air compressor that can handle at least 50PSI that can pump the air fast.
