Nitto Ridge Grap pressure

[EPHsurgeon]

Searched forums but could not find specific answer. Just mounted some Nitto ridge grapplers in 35 12.5 20 and wondering what tire pressures people are running. Mostly street and bombing northern Maine dirt/gravel roads.

I'm running the metric size equivalent with Terra Grapplers and the same type driving. I run them at the stock recommended pressure. Seem to ride well for me.

Same wheels too, just Bronze instead...

I'm currently running 36 psi cold with my Ridge Grapplers.

I run about 38 front, 36 rear on mine. I up the rear to around 40 when towing.

I run 36 cold front and rear heats up to around 39 to 40.

Have 15K miles on them seems to wear even across

I was thinking the same, I have always run around 38.

Of course the tire shop filled mine back up to 48, any issues with running them that high?
I will admit the truck seems to ride better with them higher (on the street). Get a little more bounce, but its not unbearable

Hit a bump with just one of the rear tires and you might end up pointed in the wrong direction with that kind of pressure in the rears and nothing in the bed.

Also tire wear will be horrible.
