This is one reason that the tire pressure monitors are so essential. You can monitor the pressures and temp trends on your tires both hot and cold so you know what the tire pressure should run under "normal" operating conditions (IE: when they are hot). That way you know if you need to add a couple pounds of pressure to one or not.

One other thing I also do is make the rounds and touch the bearings with my hand or laser temp them at every stop. Not a bad idea to also take out your phone and use reverse camera to look at the springs at least once a day....

We have the ST 235-85-16 tires on our 3000RK which is one of smallest trailers Montana has made. I started out at 100PSI and didn't like the bouncing so I have dropped the pressure to 90PSI. GVW on my trailer is about 14,000 and have 9760# on my trailer wheels.

There is a difference ~~~ the 80 is rated at 4080 and 85 is rated at 4400 at 110 psi. 80s came on my new 5er and I’ll switch to 85 when due to be replaced. I run both at 105. Put 85 on my last Montana.

I believe they are load range G tires. They are Sailun tires.
