Dexstar wheel conflicting info

Your rims are likely rated for at least the 80 PSI you found on the web site. Many rims are stamped either on the back side or inside the rim. Assuming your spare rim is the same as the rest, take it down to a tire shop and have the break the bead and look inside. You could also find a phone number for Dexstar and give them a call with the model number of the wheel.

Dexstar Wheel is a wheel company, Dexter is an axle company.

On our 5er, the. Spare rim is not the same as my 4 on the ground.

Make it short a sweet and call Dexstar customer service number.

I did. Apparently they only have one person there that might be able to help me but she is out off the office. Probably the same person that never answered my email.

Assuming your trailer is not getting any heavier, you don't need to run higher air pressure in the D tires. The same pressure carries the same load in the same size tire. I put E rated tires on my TT and inflate them to 50 psi since the load is not that great.

You seem to have some embedded misunderstanding here....
Have you had the trailer over a scale?
If not, then do it. Use the table on the tire manufacture's site to determine the correct inflation.
The sole reason that the rims and maybe the tires both specify a maximum inflation of 80PSI is that any higher pressure may be dangerous. It is not a suggested inflation.

A tire with a higher than needed load rating will be no issue. This is common these days as manufactures are cutting the number of ranges because improved technology means that tires can now handle higher load so there is no cost reduction for the lower load tires.

Example:
For our coach, a load range D would be safe. But I run only load range E tires for one very good reason. They are more available and the same price as LRE tires.

A gentleman was telling me that his coach (like mine) handled and rode terribly. I drove it, and he was right, it bounced around like a BB in a bathtub. I asked the tire pressure and he told me he had set them to the recommended on the rim or tire.....
When we let all the tires down to where they should have been, the ride and handling were much improved.

Keep after them.
We have 15" trailers wheels out here with 50 psi max....65/70 psi max....80 psi max. Thats why its important you find out which psi wheels you have.
I've seen the result of over pressure in load carrying wheels (truck and trailer) when I was on the road. We had newby owners/operators that thought all 16" wheels were 80 psi rated and all 15" could take 65 psi. Today most all new gen 15" 6 lug wheels are 80 psi. My current '97 trailer came with 15" 6 lug Dexters BUT are rated at 70 psi max.
Steel wheels usually split around the bead seat flange and aluminum wheels can crack the valley or the bead seats from over pressure when loads are added.

I called them again and finally spoke with someone with the info I needed. They haven't changed the design or manufacturing process of the 6 year old wheel that is still in production. The wheel was retested a few years ago and is now certified at 2200 lbs. I forgot to ask what PSI the wheel was capable of but I am assuming a 2200 lb wheel is capable of the 65 PSI required for a D load tire.
