to the OP, you’re very unlikely to need them on the highway if you have 4wd and good tires. But I would certainly have chains for all 4 tires in the truck for 3rd season. It can easily dump a foot or more during 3rd season, when the snow starts to accumulate off the pavement chains make all the difference, especially in a pickup in my experience. Hunting is more fun if you don’t spend half your time trying to get unstuck. By them early, make sure they fit your tires and practice putting them on, maybe make it realistic by putting them on in the mud while your wife dumps ice water on you...
