So I went and got my G-614 and my new 110lb rated wheels. 14000lbs of trailor and nobody seems to know exactlly how much air to run in them.

Is it wise to run at maximum trailor pressure?

When running at max the tires will run the coolest and with least rolling resistance.
Now this next part is my opinion and only that:
At one time when Radial tires first hit the market, car manufacturers ran them soft for that smooth ride (I'm sure many of you remember the first radials you saw on a car looked like they were almost flat). But because of the sidewall flex and the road holding ability of radials running at that lower pressure created a dangerous situation (now radial run higher pressure than bias ply). If you went into a curve too fast, the tread would stick to the pavement, the sidewall would flex (like it was designed to do) but if you didn't have enough pressure to keep the bead on the rim you could roll the tire right off the rim (I have a friend who rolled his Pontiac Sunbird when he rolled a front tire off the rim). We all know the side forces applied to our tires on our rigs, so to me the same principle applies, you need sufficient pressure to ensure the bead stays intact on the rim during those sharp turns and those 90 degree turns getting into the prime CG spot.
Discaimer: This is my opinion, as I am not by any means a tire expert, you must follow your heart and do what you deem best for you and yours.

Hi Jim,

Short answer is you can but you base air pressure on load.

Here is a great reference:

http://www.goodyearrvtires.com/tire-...n-loading.aspx

While on this page you can download the "Load Inflation Table".

I used the Tire Load Inflation Table listed above when deciding at what PSI I was going to run the G614s. I was not fully loaded when when each wheel was weighed and on average they came in at 3250# each. So I run the G614s at 95psi. Only 6k miles on them so far and are showing no signs of wear. @68mph with outside temps around 105* I only saw an increase of 8psi on the tire monitor. On the E rated tires running at 80psi I would see an increase of about 12psi at the same speeds/temps.

Common sense is a huge part of driving. Some got short changed in this department. Just like everything that goes up must come down, everything vehicle that moves must also stop.
