Got the '46 off jack stands, and getting ready to go for the first run of the year. All fluids checked, battery off tender and ready to go. Aaah…. may as well check the tire pressure. Well now. All four, including the spare, were at 28 PSI when it went on the stands last October. This May 1st., they are all at 21 PSI. I am running 6:00X16 WWW with tubes (I know, radials are better) filled with air. The reason I mention air, is that both our daily drivers tires are nitrogen filled, and the never seem to lose pressure. So I guess the "sales pitch" we get at the tire shop, that nitrogen is better, seems to hold water... or nitrogen at least. Seems it has something to do with molecule size difference between air and nitrogen. Odds are that offshore innertubes don't help either. Just an observation to read while we are holed up. NO! don't say holed around tires. It's bad luck.
