What air pressure are you running on road with 37" tires? I am running 35psi on 37" nitto mud grapplers. Am i at the right psi?

every jeep has it's variables as to what psi is right.

the only way to know for sure is to chalk your tires.

i have our psi @ 42psi on 37s

the common psi for 37s is between 26-32

Best way to find out is do a chalk test. With those tires you will probably end up closer to 28-30 psi
