Tire Pressure For 285 70 R 17 BFG AT TA KO

Running 285 70 R 17's on my setup they are running great. Question is what are you all running your pressure at?

The tire side wall calls for 65psi cold and that just seems way to heavy. They are load the range D tires

I originally had them at 45 leaving the tire shop and noticed a slight searching of the tire(a little more vibration than normal). Bumped em up to 60 where they are at now and they seem great it eliminated that issue but seems very stiff. My thought is to try 55 or 52 psi and find the sweet spot

Thoughts ideas and what your running your bfg at's at?

Thanks

 

the response youll get is to do the chalk test...

...i haven't done it myself, but I am running 34psi in my 265/70/R16 Load Range D BFG A/T T/A's.

I really need to get some chalk though...I'm just never anywhere i can buy it...and i really don't want to make a special trip to get some...
