I am thinking about getting a 5 gallon portable air tank to keep in my trunk for filling up tires. Does anyone have experience on how many times you can typically use them to top off low tires before they need to be refilled? The one I was looking at is 5 gallon and holds 125 psi. I seem to find my tires down to 20 psi and I usually add to around 35 psi... Any idea how many times I can do that?
