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...

Short answer is no, 1 PSI is a bit.. er,, Anal as they say, 10% is a more accurate acceptable range or better +/-5%,
But the closer to ideal the longer your tires will last.
Here is a suggestion:.. DO you know the meaning of the word interpolation?
For example: at 100 PSI a 22.5" Mitchlin XRV single tire can hold 8910 pounds, and at 105 PSI the same tire is good for 9220,
but what happens if you have 8980 pounds on the wheel? (Interpolation can give you a pressure but the chart is only done in 5 PSI steps, oh, I'd use the higher pressure (105) for that one).
And many like to add 5 PSI just for fun.
And yes, for ideal tire life (never an issue on an RV) you need to be +/- 1 PSI
HOWEVER, this has to do with tread life,, Most RV tires are relaced not due to tread life but due to shelf life,, Mine still have many thousands of miles of tread life left, but are due for replacement due to age.
