Here is possibly the most random question. What is the recomondation for checking your tire pressure (meaning how often, not how to do it)? I have never heard anything, and even after checking the paperwork from the tire manufacturer when I bought my tires it just said "often". What does that mean? This is strange I know but I was just wondering.
Thanks

The Tire Rack has a number of web pages devoted to this topic- for instance;
Better grab a cup of coffee first. Lotta pages to peruse.
Personally I check the tire pressure almost every week. I have a slow leak in one of them so I am forced to do that since I am too cheap to get it fixed.
I also check the tire pressures when we have large swings in weather temperature. Since I live in the Mid-Atlantic area that is more often than most places in the USA.
I have heard of people who check their tire pressures at every fuel fill-up, but I don't do that.
When I had the first rotation/balance done on our Avalon, Costco switched to Nitrogen for $1.00/tire - so I am trying it. Only been a couple of months but pressure is within a pound of initial.
Use air in the Highlander and riding mower so check about once a month. Mower loses more air than Michelins on the Highlander!

Did Costco explain why they thought that would sell? IIRC normal air is around 80% nitrogen, 18% oxygen, plus 2% of odd gases. Is there so big a difference, especially when you consider Costco is unlikely to be selling gas of laboratory-grade purity?
I figured if it was good enough for airlines and NASCAR and for only 4 bucks what did it hurt to try it?
I've read nothing negative about it, reviews are mixed. So far in about two months my tires are within 1 lb. They are Michelin OEM MXV-4's by the way.
