I bought a can of "Fix a flat from Auto Zone." I also bought and carry a 12 volt tire inflator I got at Sams Club. It fits in the cig. plug between the seats. It has a light on one end and a pressure gauge on the inflator side. I also bought a self sealer - plug kit that you use to seal the hole in the tire if it can be sealed in the field. Hope that helps. Also get towing insurance or AAA for the vehicle. Just might help. Be safe .
A system alright, can, hose, valve. j/k.
Just f.y.i. if you ever have to use it make sure when you fix the tire or even if you don't have to, have a tire store take the tire off and clean the fix a flat chemical off it since it is very corrosive and will damage your wheel.
