Nitto Ridge Grapplers

[AZJLU1100]

i am currently running 35x12.50/R20 on my Rubi. I would like to get input on what I should run my tire pressure for on road driving and what can I safely air down to for moderate rock climbing. Thank you

I run a smaller ridge grappler and did the chalk test (search the forum). On road I am running about 32psi per the test. I have dropped them to around 20psi off road (nothing aggressive) without any issues.

Very good looking rims and tires!

I'm running a different size but I'm also at 32psi for on road. I'm sill messing around with tire pressures and haven't found the sweet spot yet.

Something to be aware of is that the ideal pressures for your tire is also dependant on the width of the rim. Both on-road and off-road.

I usually run my 35” Trail Grapplers around 36 on pavement in warm weather. When its colder/wetter/snowy should I be airing down (to what range)? I have more testing to do, but I did feel like my tires were slipping more than expected in rain/snow last winter.
