Just got a set of bfg at ko's.. showed up at the house yesterday.. they are 285 70 17.. anyone who has these.. what is the best tire pressure to run these at?? just waiting on the leveling kit in the mail until i can put them on the truck. thanks.

 

Those, according to the site are a load range D with a max 0f 65, (size is relatively meaningless). Run them at about 45. That should handle daily and anything you haul up to overloading. I would not go any lower than 40.

 

I've always had good luck with 40psi in mine.
