I've always OVER inflated my tires by about 5 psi from the sidewall.
I've driven nearly 1 million miles on tires that were overinflated. NEVER had a blow out. Tires always seem to last longer too. They also get about 1mpg more.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.

I don't know, you start out saying you know more that the tire companies, then...

You say that you don't think the builder knows as much as you know. Then you say you don't want your tires to get over heated.
Maybe you should do what the tire manufacturers tell you to do - weight the four corners and air up by the tire manufacturers pressure table. Cause the builder has no idea of what tires are on there now, or what rating the tires have because they may have been replaced with different tires(And you are right about the builder on that respect), or how much water, fresh or waste, and how much other stuff your hauling around. But if you don't care about the tires, don't bother maintaining they the way the manufacturer says.

The MAX preasure on side of tires is 110 psi. Is it ok to just run em at that preasure? No, I'm not goin 2 get it weighed. No, I'm not going to mess with manufacturers Tire preasure tables.
I'll be traveling across the US to Colorado & there will probably be temps into the 100s in Kansas, etc. The preasures listed inside the coach by the builder (85) seem very low. I don't want the tires to be overheated if preasure is too low.
Why ask a question if you already know all the answers? I bow to your superior intellect and will watch for the accident report you surely will generate.
Since you obviously are enough of an expert to determine that running tires at maximum pressure will potentially cause an accident, please then explain from a scientific view point how this accident could/will occur.

What is imprinted into the sidewalls is the MIN pressure needed for that tire to carry its MAX load...

The inflation pressures on the placard are what are required for the coach to carry its MAXIMUM weight...coach; contents; people...whatever. You inflate to 85 and check to make sure they stay at 85....and you wont have any problem regardless of the outside heat

Man you guys came down hard on him. Why? Go back and read the original post again. I didn't see anything stupid about the question(s).
There is no need to run maximum pressure if the tire is not at maximum load. So how would YOU find the correct pressure for the tires without tire tables or weighing? That was the question.

Or resources, did you ever think of that? May not have time between now and when he leaves, particularly if there are no scales that he is aware of anywhere near his location. Is one to assume by magic that a set of scales will just pop out of nowhere along his location.
There are certain subjects on RVnet that bring out the worst arrogance in so many otherwise nice people.
Thanks to all that replied with usable info. To those who I, apparently, angered by asking a question, I'll not bother you again. Also, Thanks to whoever it was that was so worried about my spelling.
