I know that we all have tire safety on our minds and with that thought I have a question? What size compressor should I buy? Now the background, I have a small class A and I was hoping to find a small compressor that will give me the 95psi I needed to top off my tires, but when I look around at Sears etc none of the ratings make that much sense to me. Should I get a 125 psi compressor with a one horse motor or a 150psi compressor with a .65 motor. How important to fill a tire is the size of the tank? All these questions I am so confussed.
