Look at the tire sidewalls, it tells you right there.

i have looked and can't find it , the tires are MISSION 225/75/15 D LOAD

Somewhere on the side-wall the manufacturer states their max recommended cold inflation. (in this case most likely 65psi) If you have the original tires it is time you seriously considered replacing them. The size you gave is not complete. Does it begin with ST and are they bias ply or radial. (ST225/75R/15D would be a radial trailer tire) In '05 Keystone was still using bias ply tires. (ST225/75/15D) If the tires are over 6 years old they (and definitely the valve stems) should be replaced.) JM2¢, Hank .... I think there was a recall on those Mission tires ????

That's what is stamped on the tire and is valid for "maximum" tire pressure at "maximum" load. There is a yellow sticker on your RV that gives the tire size and recommended inflation pressure. On mine, it's on the Road Side Front. On others I've seen it's on the screen door along with the Manufacturer's sticker. Both the sticker and my tires have the same info, but others may differ.

Doublecheck that both have the same info. There's an active post right now alledging that Keystone apparently placed the wrong information on the sticker and caused overinflated tires. I am not certain of the outcome of that situation.

I'd verify that all the "numbers" recommend the same thing. Then you can keep the tires inflated properly without wondering what's what.
