Tire pressure....again
OK guys, I am thoroughly confused. Our right front tire has recently, in the past several hundred miles, started wearing on the outside. First thought was alignment, but the wear pattern is not typic...

Pressure on sidewall is max cold pressure recommended by tire mfg with a full load also matching sidewall data.
Pressure on camper placard is what camper mfg recommends with full load the camper is rated for.
The camper mfg pressure would yield even weight distribution across the tread and the tire should wear out in an even fashion.
Too much pressure for the load will cause the tire to wear in the center of the tread.
Too little pressure for the load will cause tire to wear on the outside edges and may overheat the tire and lead to failure at speed.
Tire pressure should always match the load although in the real world, that can be tricky.
More pressure (as long as it does not exceed mfg max cold pressure) is more desirable than less but makes for hard ride and center tread wear.
Never 'bleed' air from hot tire even if pressure is above sidewall numbers. Remember, sidewall max is cold. Mfg expects tire pressure to increase with temperature. Tire set at max cold pressure will never increase pressure to the danger point while running unless the tire is grossly overloaded.
