Recommendations for tire pressure on ridge grapplers 285 70 18?

Ideas anyone? Thanks.

 

40 psi on the road. 25 off road. More for towing.

 

45 front, 35 rear and adjust depending on terrain or payload.

 

Do a chalk test, takes 20 minutes and you will then know the right pressure for your particular truck, setup, load.

 

Shit 25 isn't offroad pressure, that's street pressure on some of my trucks lol

 

Email Nitto with truck info as well as tire and wheel info and they will give you a starting point. Be specific as possible so specify crew vs double cab. If aftermarket wheels size, width, backspace, and offset. Anything you can think to tell them.

 

44 at all 4 corners.

 

Will do thx guys.

 

X2, 40 psi on all 4 on mine

 

All 4 corners are 38 on mine.

 

I run cold pressures of 44 front and 39 rear in mine. When towing or hauling a significant load, I will raise the rear pressure. These 5.7 motors are heavy...you need more pressure up front when empty. Like others have said, do the chalk test to confirm.

 

Yeah I get it, but so far I don’t have an air compressor so I drive it home on whatever I’m running and I mostly drive forest roads instead of full on off-road tracks (a bit hard to find an unmaintained road that’s open around here).

 

I have one of these in the truck. https://www.lowes.com/pd/CRAFTSMAN-...le-Electric-Pancake-Air-Compressor/1000595167

 

I run 44 psi on all corners as well.

 

I run 40 on all fours unless I am taking a trip over 300 miles with the back loaded down then I bump the rear up to 45

 

Impressive to have something like that onboard. I’m thinking more along the lines of viair or arb both 12v powered.

 

Chalk test will be pretty accurate
