Extreme Cold Tire PSI?
I am running 35 X 12.5 Micky Thompson Baja Claws. I live in Nunavut where it gets to -50.
I am currently running at 12PSI becuase there are no paved roads and it makes the ride smoother.
On the tire wall it says 70PSI COLD or something like that but realistically, what should I run at in extreme cold?
Thanks.

run the same pressure as you run now, I live in fort st john and we regularly see -40, you get flat spots but they go away quick. I am running 35x12.5 procomp x-terrains and I usually run 20psi all year round

Why would the sidewall say to keep at a high PSI for COLD?
It can get to -60 here without wind chill on some days.

12psi seems low enough to cause sidewall damage with extended use. Maybe not, I can't see the tire.
Anyway, run what works without damaging the tire. Bring the pressure back up when the cold temps cause it to drop off.

If that's a celcius temp, it is actually warmer than -50 farenheit.
The temp scales meet at -40, below that the F temps are colder.
(maybe I've said that backwards somehow, but you get the point)
Not that it matters too much in this topic, just some trivia I guess.
