From the Carlisle Tire site: "What is the maximum psi limitation for your trailer wheels? Max air capacities are typically a function of the tire, not the wheel. Unlike tires, the load rating of a wheel is not generally dependent on the operating pressure. The wheels themselves are manufactured and tested to a load rating (without consideration of pressure) and can safely support that load. As long as the load is within the limits of our wheel's load rating in pounds, our product will perform as expected."

My wheels are stamped with a max PSI of 65, noticed it when I last changed the tires. So yes some wheels do have max ratings.

I guess my tires have around 7500-8000 miles put on them in their first year. I keep them between 75-80 psi always. I keep a cover on them when they're at home.

They still look like new. Probably at least 80%-90% tread still.

If you're 2k lbs under your gross,....run the max pressure. If you were several thousand under,...then it'd be a different story.

Max always.

Towing my toy hauler with LT tires for 13 years. Always max pressure.

Run max pressure!!

2nd that!

From Discount Tire:

Inflation

Always inflate trailer tires to the maximum inflation indicated on the sidewall.
Check inflation when the tires are cool and have not been exposed to the sun.
If the tires are hot to the touch from operation, add three psi to the max inflation.
Underinflation is the number one cause of trailer tire failure.

Load Carrying Capacity

All tires must be identical in size for the tires to properly manage the weight of the trailer.
The combined capacity of the tires must equal or exceed the Gross Vehicle Weight (GVW) of the axle.
The combined capacity of all of the tires should exceed the loaded trailer weight by 20 percent.
If the actual weight is not available, use the trailer GVW. If a tire fails on a tandem axle trailer, you should replace both tires on that side. The remaining tire is likely to have been subjected to excessive loading.
If the tires are replaced with tires of larger diameter, the tongue height may need to be adjusted to maintain proper weight distribution.

I don't load my trailer to the max, but I air my tires to max psi.
