Are Our Tires REALLY that sensitive?
I know I will roust the ire of many a tire aficionado, as well as those who will claim expert knowledge from years of traveling and RV'ing and quasi-engineering or actual engineering status/certificat...

Are you saying that when your tires which would have a 100psi cold tire pressure leak down to 75psi, you stop? In other words 25 psi below the minimum cold tire pressure.
You're kidding, right? :h
I am not kidding. My tires do not lose any air, not ever, unless a failure is in progress. I do of course monitor the TPMS always. The air pressure on these tires fluctuates a LOT. Depending on outside air temp, and if the tires are hot or cold, pressure changes are crazy.
In this bus, with the new sumitomo's I put on a few years ago, I only have needed to put air in the tires in the spring coming out of storage. I credit that to getting rid of the extenders, they've been known to leak...lol. just a bit. sometimes...
I'm not running around chasing my air pressures. 110 / 95 cold tires at 70 ish ambient is good. All the fluctuations, I don't chase them.
