PSI on 245/75 E loads

I'm looking to put new tires on at the end of summer and would like to know what pressure folks are running on road. The Falken Rubrtreks are my first choice and state a max pressure of 80 PSI. E load at 80 seems brutal but how much lower than max is the sweet spot?

Another minor factor in all this is that I carry a Viair 85P which has a working max of 60 PSI. It's plenty to get me home but I'm hoping the pressure you all like is less than that so I can air down and back up with no extra stops or a new compressor.

 

43 psi is the adjusted recommended psi for that particular tire.

 

I missed that in the research. Bonus for being under 60!

 

I run GY MTR in 245-75-16 10plyE on my wife’s Jeep TJ Wrangler at 30psi and they are wearing perfectly flat.

 

Excellent. I appreciate the help.
