Deep snow? Any tire rated for the truck of the stock size. With good Chains on them. The front has limited clearance so you must prefit the chains and use extra binders. Rear has plenty of room. I run Skid steer type chains on rear and very tight fitting V-bar on front. But the front can use other types of chain. S-type with built in adjuster, Heavy cable, Even the Skid steer type in an emergency.
The stock size for my pickup is 265 70 17. I use 245 75 17. They're the same height and load rating but a couple inches narrower. That gives a lot of extra room for chains.
