Air pressure in tires and GVW
I've seen several posts that refer to adjusting air pressure in the tires based on vehicle weight. How does this work? Is it the heavier the rig the higher the pressure should be? If my rig weighs ...

or just make sure you are under the weight limit and fill to the pressure on the sidewall and think about more pleasant stuff.
Yup, this works very well if your chassis maker left you very close to the carrying capacity of the tires (i.e. very little safety reserve).
But, if you have actual weights are well under their carrying capacity, your PSI could be well above the minimum recommended by your tire manufacturer.
So, there is really no "we know this will be what the tire manufacturer recommends" unless you weight your coach's axles and much better the individual wheel positions.
