Kmc Machete 17"
37" Trail Grapplers 27.5 psi

 

Nitto RG's 27fr 26rear 37x12.5x17

 

I run 28 psi in my 37" Ridge Grapplers. They are D rated. I ran 26 lbs in my last set of E rated Trail Grapplers. A chalk test is the best way to figure out the best pressure, as tire load ratings and vehicle weight make a big difference.

 

17" ATX Slabs
37" Nitto Trail Grapplers - 30psi on street.

Have not done the chalk test... im gonna look into this. Thanks

 

I run 32 psi in my 37" Nitto Ridge Grapplers. I ran the same in my 37" Toyo Open Country RTs.

 

I have never run tire pressure this low before... is 30 and under PSI on the street what Nitto recommends with these tires? Before my current 37s the biggest tire i had run was a 35.. even then i think i was running at mid 30s. From the looks of it, and i have not done a chalk test yet, but i may have to drop down to around 26 or 27psi.
