Nitto ridge grappler PSI info

I you call nitto tires and tell them what nitto tires you are running and what trim tundra you have they will tell you the exact PSI you need to be running for your specific application. A sr5 tundra 4x4 with 285/55r/20 calls for 40 psi in front and 43 in rear.

 

Does your tpms sensor kick on?

 

Nope so far so good

 

the ridge grapplers are on my short list for my next set of tires...

 

I have mine set at 45 all around, i hadnit at 37 in front and 40, when i was driving it was damn noisy. It feels better at this psi for me. I have 285/70/18. Im probably going with the falkens next.

 

Too noisy , just curious.

 

Mine are super quiet..Tire guy said keep them at 45psi..305/70/17. Was looking at Falken at3w but I spend a lot of time on gravel roads, I tend to avoid A/T tires due to them picking up and throwing rocks all over! M/T tires are too damn loud! Ridge Grapplers have been a perfect fit for me.

 

Sorry to jump but does the tmps light come on at 40 psi?

 

Mine doesn’t..

 

285/70-18 been running at 44psi cold all around currently.

Nitto advised 36 up front and 38 in the rear when I just spoke with them.

 

Mine didn’t

 

You can reprogram the PSI parameters by holding down the button on the dash below the ignition.

ETA see now your 2nd gen. Not sure if this applies.

 

For me:

44 front
44 rear

 

This will be my second set of Nitto Trail grapplers AT. Not noisy at all
In my opinion.

 

I find that if I run higher pressure in the rear gets very bouncy. I actually run less in back. E rated tires, not nitto though.

 

That would be because sensors are set for the OEM tires. With OEM KO2s mine comes on below 46

 

I'm running the same size at 44 psi.

 

To me it’s seems like the proper psi.

 

This is a good setting not to soft or hard

 

I’m usually running 45 psi bc I tow often also

 

Running 45 on my 295's, as for noise, very little. It's been a great tire

 

Anyone else running 35x12.5r20LT F rated in ridge grappler with CM? If so, what psi?

Dealer had 36 psi all around and it seems pretty low.

 

45 PSI

 

For reference, Nitro recommended 34 FR, 36 R when i called them. I'm planning to do a chalk test as well...

 

50 in mine but I carry a fwc on back.

 

I’m running 35x12.50x17, ran 32-33 cold for quite awhile, feels good around town, maybe a tad soft in corners, bumped up to 36 and it feels about right. Ran them home 5 hours right after I got them at 40 and they felt too hard, but they were brand new so that could have been it.

 

I’m running 285/75R18LT Ridge Grapplers at 43 psi all around….. no lights….. minimal noise….. ride is great…… chalk test shows even wear…… had them on for 24k miles at this point and still look new…. Rotate them with every oil change (6k miles)
