need opinions on tire pressures

So, do all who run lower than max pressure in a trailer tire in order to match the weight of the trailer to the PSI in the tire also always run your trailer across the scales before leaving on a trip? Seems like you would need to in order to make sure your weight is exactly the same as before? And if you carry a full tank of fresh water, do you let air out of the trailer tires at the end of a trip since the trailer doesn't weight as much?

Another question. Do you weight each tire separately? Or do you weight the whole trailer and divide by 4, and air each tire to the same PSI? Since no trailer is ever loaded to the exact amount on each tire, couldn't some of the tires be "over inflated" and other tires be under inflated if using a inflation chart?

I know that having less air, even if allowed by the manufacturer, gives less load capacity. I prefer having extra margin for error rather than less margin for error.

I have always tried to keep the max air pressure as called for on the side of the tire (50# in my previous LRC tires, and 65# in my current LRD tires).

No need to run max psi unless you want to beat up your trailer with a harsher ride and have uneven tire wear. Goodyear has a psi chart for your Endurance tires and they recommend 40 psi for a load of 1530 pounds per tire. You can find the chart HERE

Seems Goodyear isn't much concerned with sidewall flexing, heat build up, and such with these American made tires.
