Tire pressure?

With no disrespect Cracker, I believe Howie is simply stating that tire engineers know more about their tires then Airstream engineers do.

Thanks Sky - and no disrespect taken - but I would still contend that Airstream, especially with respect to the newer trailers, is far more capable of properly sizing their tires and determining correct pressure than any of us could hope to be. That said, in the absense of up to date data for many of the antique (---or older trailers,) and based on the emergence of new tire technology since many of the older trailers were built, the tire charts, the determination of axle rating, and weighing the trailer, is definitely the way to go. Nothing I said would suggest otherwise. One caveat I did want to repeat, with respect to Goodyear Marathons, is that Goodyear does not recommend any pressure below 45 psi - even though their charts will show capacities all the way down to 15 psi in the case of ST Metric Tires. I'm not sure where that little tidbit resides - but I have definitely read it.

Do not under any circumstances pull into a weigh station on the Interstate or any other state or federal weigh station because if you don't have the tow vehicle licenced for the proper amount of weight, there will be a fine. If you are over the Combined Gross Vehicle Weight Rating for the tow vehicle and or trailer, you will not be allowed to proceed until your rig is in compliance with the manufacturers specifications.
There is a local horror story about this very thing.
Go to a CAT Scale, a local moving company, scrap metal company or any body and pay to have you rig weighed.
That way there are no suprises.
