Tire pressure question
Hi all. Apologies again for being the guy that seems to be asking too many questions. I am taking the safety of my family very seriously, so please no guy slapping himself in the forehead icons... ;...

Many tire manufacturers have inflation charts on their web sites. They typically recommend max inflation if running max tire weight rating. But if the actual weight is less than the tire max rating, they recommend lower pressures. Too much pressure will tend to round out the tire making it wear faster in the center. Too low pressure will tend to make it wear faster on the outer edges. Ideally you want the pressure where the load will be distributed evenly across the tread for max traction and even wear.
From the Towmax web site:
When it comes to maintenance, keeping your RV tires inflated to the proper pressure is the most important thing you can do to insure their long life. Follow the guidelines in your RV owner's manual if you have one. If you don't have an owners manual then asked an expert, either a good tire man or your RV service tech.
The maximum pressure allowed for a tire is embossed on the side wall. That's the maximum pressure when the tire is cold. It's okay for it to be over that by as much as 10 psi if tire pressure is checked while hot. However, always check air pressure when tires are cold for accurate reading. The proper pressure for your RV tire may not be the maximum tire pressure. The right pressure is determined by the weight carried by each tire on the RV and the pressure recommend by the tire manufacture for that weight.
Running a tire in an over pressure condition will cause uneven tread wear. Running a tire in an under pressure condition will also cause uneven tread wear and can cause damage to the side walls of the tire. Keep in mind that a tire can lose as much a 1 psi per month and as little as 5 psi can make a difference in the load carrying capacity of a tire. So, it's especially important to check and adjust your tire pressure before taking your rig on that first trip of the season. Then check tire pressure once a month.
