Sidewall says max pressure is 65 so just curious what everyone suggests psi should be for winter conditions? I've read posts going anywhere from 32-45psi so not sure what to set to as they're my first set of chunky rubber.

Thanks for any help

Whatever is needed for the weight of your truck. For example, if your rear axle rating is 4000 lbs then I wouldnt go less than 40 psi on that tire.

The rating is 3195 lbs at 65 psi. (40/65)*3195 = 1966 lbs. While its not perfectly linear like that, it gets you in the ballpark.

I literally just saw a post the other day of a guy with a Tundra whose tires exploded on the freeway. They were 80 PSI LT E range tires with a 3000 lb load rating. I would bet money the guy was running them at like 30 psi and was WAY over the capacity of the tire at that pressure.

The best way to figure it is to do a chalktest. I can tell you on my SCab, 6.5 box, 4X4, 9.75 axle. I listed it like that to show all that, and likely more, makes a difference. Your truck might be more, maybe less.
The chalktest is likely the most accurate way, I can tell you what I run with that particular truck, and tires.
Mine are and have been these sizes and pressure; bear in mind, my 150 is used as a blacktop queen, usually nothing more than myself, two dogs, and a load of groceries.

305/70/17 LRE the same; 38 front/36 rear.
