Tire pressure Cooper ST MAXX

[E9taco]

Just got some Cooper ST MAXX in 255/85/16 and was wondering what tire pressure folks are running these at? I have a canopy, sliders, skids and a rear bumper. The ride is noticeably stiffer then with my C rated Durotracs. Im currently running them at 30-32psi. Love the tires, just looking for a little advice.
Aloha

Chalk test would be best way to adjust them

Thanks Rob. You have these tires right, what pressure have you settled on?

I'm running 285s.

I run 31 cold for better grip.

Been watching wear with no issues

Been running that exact tire for 2 yrs now. Im running 32 front 30 rear. Only con is hard pack snow they do get squirrely, ive went to a 2nd set of blizzak's for the winter months. Ill be switching to general grabber atx when its time for new shoes.

Before I had bumpers I ran 32 front and 30 rear as well but with full steel bumpers and skids now I just have them all to 35 but am yet to chalk test, probably gonna do on my next day off
