When I'm towing my 5er, I put about 75# of pressure in my rear tires. When I'm not towing, I take them down to about 45#. When we go on trips where we stay in the same campground for several daysor weeks, I'd prefer to deflate the tires to 45 rather than leave them with the higher pressure. It's a real pain in the butt now adays to find convenient places where you can get air, so I am looking at a 2 gal air compressor that I can take with me to eliminate that inconvenience. Is two gallons big enough to add that much air to a couple of tires?
