The pressure on the sidewall of most RV tires is NOT the maximum it should ever have! It is the MINIMUM to support the maximum rating of the tire!!
ON TRUCK size tires the cold pressure on the sidewall is the MINIMUM required to support the maximum weight rating of the tires. Same with the tire charts, it's the MINIMUM cold pressure to support the weight. So YES you can exceed the pressure on the sidewall by a few psi

Wow I'm so glad that I know what psi to put in my tires because this thread would have surely confused me. Ok now when you look at the sidewall of your tire and it reads max tire pressure, this means MAX TIRE PRESSURE.......this means for example if it reads 110 max psi, by no means are you to exceed that pressure under any circumstances. And to repeat myself about the tire charts..... if you look up your coaches weight and the chart suggests 100 psi, that is what they recomend for your coaches weight.
Under inflation is the number one cause of tire failure so for sure don't go under the 100 psi.... but technically speaking, going over the 100 psi recommendation means you will be overinflated and subject to possibly a harsher ride uneven tire wear and more prone to punctures but it is not as critical as going under inflated.
