PSI with aftermarket AT tires (265/70/17)???

Discount tire says to run 29psi in the General AT2 tires I got(they are going by the door sticker)
I've always ran around 31-32psi in all my AT tires ? The values on the door are for the 265/65/17 stock tires but im guessing 29 is a bit too low?
I can do the chalk method, but usually go by feel as well. I also very rarely carry anything in the bed except surfboards or bicycles.

I'm probably opening up a Pandoras box asking what folks are running but....

 

do a chalk test

Are they E load or SL? I'd do 32 front and 30 rear if SL

 

Second on the chalk test.

So many different variables are at play when it comes to proper PSI: vehicle weight, weight distribution, altitude, weather temp, tire load rating, etc. It's one of those things you have to experiment with.

 

Do the General tires have a recommended pressure on the sidewall?
