WEll this is true that if I take a football with 13lbs of air at say 65 degrees, then take it outside at say 25 degrees the air pressure will decrease because of Boyles law which states that pressure is relative to temperature. But once I bring that same ball back into the 65 degree room the pressure will go back up, if I take it into a 85 degree room it will increase. so that theory does not really hold air.

I’m in Virginia right now. The temp has been flunctuating pretty drastically this last weekend. It has gone from almost 70 down to the 40s and back up to 70. All 4 tires on my car dropped to between 20 and 30 psi when it got cold and didn’t go back up. They’re new tires too.

As noted down below a car tire (tubeless) is more porous than the football liner and will let air out faster plus a car tire is under over 2 tons of weight and football is not, but if you are losing 20 to 30 psi something is wrong with your tires, I am in Kentucky we went from 65 to 14 degrees in 48 hours and my tires dropped about 3 psi. My tires only hold 35 psi???? The average car tire holds about 30 to 35 psi to be fully inflated.

Some places use nitrogen, I think if you have a green valve cap it is filled in nitrogen, supposedly it is not affected by the temps as much as just atmospheric air which is about 78% N, 20%O and the rest is CO2 and other trace gases.

I'm not current in what " Black & Right" or "Black & Blonde" means, but as far as tire deflation in cold weather...isn't that broadly known common knowledge?

Mine historically deflate from 32 PSI to 24 on their own, unless one has a loose valve or bead seal and it may be outside the bell curve. Every year, without any outside interference.
