air pressure, dirt roads
Hey all. I am going to be running 37x12.5x20 nitto trail grapplers on my 350. Anyone play with tire pressures with them? I am trying to get a good starting point for fire roads etc...
There are a couple trails that are by my in laws that are about 15-20 miles into the hills that I would like to hit up...but I have a feeling the 60 psi I run on the street would not be ideal...
Suspension set up will be 4 wheel coil overs, not sure the spring rates yet, but probably 300 over 500 fronts and 250 over 400 rears. But maybe not...
