Is that the weight per tire, another words times 4 ? And psi should be 80 psi ?

4 x 2860 = 11440 for a two axle trailer. Include the new RVIA 10 % suggested buffer and you are at 10296 for two axles.

And yes for the max rating of 2860, they need to be inflated to 80 PSI cold.

The maximum permissible inflation pressure, established by it's manufacturer, for the tire in the picture, is 2860# @ 80 PSI (single). For Original Equipment (OE) tires, the correct recommended inflation pressure for them is set by the vehicle manufacturer. Those recommended inflation pressures will be found on the vehicle certification label. In the vehicle owner’s manual or on a tire and load inflation placard, usually near the vehicle certification label.

Nearly all OE tires on RV trailers will have a recommended inflation pressure equal to the tire manufacturers maximum permissible inflation pressure found on the tire sidewall. That may soon change with the new RV tire inflation standards recommended by RVIA. I doubt it, but it could happen. RV trailer tire manufacturers have always assured us that maximum inflation pressures for the RV trailer tire is the best method.

Okay, here's the basics for inflation pressures for the replacements.

First, they must have a load capacity equal or greater than the OE tires provided at their recommended inflation pressures found on the vehicle certification label. They should be approved by the vehicle manufacturer - good luck with that one.

The new tires must be fitted to wheels/rims with size and specifications suitable for proper tire mounting and fitment into the vehicle wheelwell with sufficient clearances. New valve stems must be used with PSI ratings equal to or higher than required by the replacement tires.

If the new tires don't conform to the tire load/inflation chart for the OE tires a new recommended inflation pressure must be set by the installer. That inflation pressure must provide a load capacity equal to the load capacity the OE tires provided. Notations should be made in the vehicle owner's manual to reflect the new recommended inflation pressures. The installer has the option to develop and install an auxiliary tire placard with the new designated tire size and recommended inflation pressures. It should be affixedt adjacent to the original tire placard.

In the eyes of the tire industry, a tire designation different from the OE tire designation is a misapplication. In other words, if the OE tires are ST, the replacements should also be ST or another tire with a "trailer service only" designation.

Don't forget to register your new tires. If the name brand is not on this Tire Rack list just type the brand and tire registration in your search engine.
