I am just curious what pressure, I should be running at since I am now running 31s. I used run at 32 psi with the 235/70 and I tried that, but the tires felt really low and dragging when driving. I put them up to 40 and now they look a little too full. The max psi is 50, but thats obviously way to high. I just want to cut down on the trial and error. Maybe a ZR2 stock psi?

 

I run 36ish psi on my grabbers...works pretty well for me!

But I too am curious as to what the optimal pressure would be for daily driving!

 

i have between 35-40 psi in my 30x9.5x15 cooper discoverer s/t. i even had that in them when i went in the sand at carolina beach but next time i will lower them down a few psi.

35 to 40 on my 31" BFG ATs if you want a little better gas milage but a rougher ride ...

i was also wondering about the optimal psi for my 31 bfg mt's... sounds like it somewhere between 35-40?

 

I noticed on my 30" Baja M/T's that if they're below say 37psi it feels really swirvy on the highway. I run mine at 40psi
