35X12.50R18LT Toyo OC MTs Tire Pressure

Looking for some advice as this is my first time on 35s. Attached is a photo of my 2016 OR edition with 35X12.50R18LT MTs, trying to figure out the best tire pressure to run in them when on the highway, as I air them way down off road based on conditions. Discount tire installed them at max psi of 65, but I was thinking between 45-50 would be better on highway. Thought maybe someone had this figured out possibly, and I searched the forums but did not find anything on this. Thanks in advance for the advice!

 

You should be in the 28psi range for on-road use.

Your best bet would be to look up the tire pressure chalk test to find out exactly what the best psi for your specific application is.
