60 to 65psi is what I use.. I also use a bike pump, I air hose up slowly..I check lams and riser for alignment every few pumps. I can usually get 55-60psi with my bike pump,then I use my air compressor for the last few pounds of air pressure. I keep a spare bike pump and fire hose set up in my shop just in case..also get a pack of extra valves for the hose, it will also have the little valve tool in it, only cost me a couple of dollars..almost cost me more when I didn't have them in the shop..
