oops, forgot to mention, Thanks Grit Dog. I don't think the tires will be hurt at 80 or so PSI either, my overall normal travel weight in the trailer is about 15,400 full of water, propane, food etc.
I am comfortable knowing there is enough capacity in the tires for the trailer on it's own.
You're welcome! And just trying to be helpful.
Based on your weight (you said TT, but I'm presuming 5ver), either way, subtract the approx tongue/pin weight, which will put you around 14klbs or less actually on the tires. At that weight 80psi (cold) is aboot right, but also at that weight, I would run them a little on the high side. Just general methodology for care of trailer tires (that live a different life than vehicle tires).
Regarding Discount's "opinion", all I can do is LOL. And I'll leave it at that.
Regarding being able to air them up yourself on the road and able to reach that 80-90psi effectively, "most" 12V plug in compressors will at a minimum struggle with that from a duty cycle standpoint. Some of the upper end ones will do the job, but still slowly.
IMO, unless you're prepared to plug leaks etc and then need to air back up, it's not worth getting a compressor that will do the job well.
On the road somewhere, I'd just roll to a tire shop if I needed some air. It's one of those, be prepared to fix on the road, or that's why you carry a spare, type of thing.
If you really want the ability to air up high pressure tires even somewhat efficiently, need to look at getting a small 120V compressor or prepare to spend 2x as much for a 12V one and have a good connection for the DC power.
