And why not? I guess when air was "free" they didn't try to make it so tough to put air in your tires before your time (re.$$$$) ran out. Now with the pay for air (not complaining about paying for it) in order to get all of your tires filled correctly you need to remove all of your valve stem caps and make sure you're ready to go before your time runs out.......because that's what they are hoping for so you have to spend more money. Back in the day you just dialed in what you needed for those high pressure bias plies, brought your own tire pressure gauge and checked the dial in pressure, adjusted the pump dial to match your tire pressure gauge and then hit the other three......and still had time to check the trunk spare to make sure that was okay too. AND IT WAS FREE!! Okay I'm feeling a little better, dumb rant, but feeling better none the less
