Probably been gone over a dozen times, so I apologize in advance. The sticker on my trailer says I should run the tires at 35 PSI. The sidewall says they're good for 50 PSI.
I've heard conflicting info on this-A friend swears I should be running closer to, if not at the 50 PSI to prevent the tires from overheating/blowout. If so, WHY would KZ tell me to run them at 35 PSI? Running them at the higher pressure makes sense to me, at 35 PSI the actually look a bit low....What do you all do with yours?
If the tire sidewall says 50, then I would air them up to 50. I have no idea why there would be a 35# sticker on the side of your trailer, other than its just a mistake.

I run mine at max sidewall. Truck is at max sidewall as well (80) without any abnormal wear.
You get the max load carrying capacity at the max pressure. How close are you to be maxed out on your tires? I don't know either... I just keep it simple and keep'em full.

I've always understood the correct inflation for a tire requires weighing the axle and then looking up the correct inflation in the manufactures data. The only time to run at max sidewall pressure is if your tire is carrying it's max rated load.
My guess is KZ weighed that configuration and checked the charts to find the correct weight and that's what they recommend. I would read into their number that the axle is carrying a load quite a bit below what it's rated for which is good.
The number on the trailer is good for the OEM tires at the full GVWR of your trailer. The number on the tires is for the full maximum load of the tire (which in this case must be a lot more than your trailer GVWR)

Well, you did not say what your RV was but I will offer my opinion. I am reasonably certain you do not know what your RV weighs on each wheel when you pull out of the driveway. I am also reasonably certain that your RV manufacturer did not make your tires and the label on your RV could have been printed by someone who never actually owned a RV. What is so difficult here, use the max cold pressure the tire manufacturer placed on the tire sidewall. It will not hurt anything. The tires can make or break your next great adventure. You might get more miles with slightly less pressure but you almost certainly will run out of safe tire life long before you wear out the tires. You can, if you want, over think every issue and detract greatly from a very enjoyable RVing experience.

Depends on several items. Especially the trailer GVWR and how many axles.
If the tires are OEM size and load range you will get a cooler running longer lasting tire on the trailer using max sidewall pressures.
If the tiree are way oversized and the trailer is small then 35 psi may be better.

Hi AV8R,
This is not adding up. We/you need more info to base this decision on that adds up.
Can you tell us what year and model camper you have?
What is the GAWR of the TT?
What is the GVWR of the TT?
Does the tire placard declare a tire size and what is that tire size?
What tire size is on the TT?
Something does not seem to add up here and we are missing some info to help give you a better answer.
Hope this helps.

I weigh each wheel and then use the tire manufacturers charts to determine proper pressure. I then add 5 psi for luck.
Probably your TT manufacturer looked up needed pressure for fully loaded TT. Thus even that pressure may be higher than you need.
Works for us. No tire issues except a few repairable nail punctures in over 200,000 miles with non-Chinese ST tires.
