Quick update. I went out of order on the work sequence and got tires put on my new wheels. I got the wheels a couple of years ago and was waiting until I got a little closer to driving the truck before adding tires and putting them on the truck. At this point, the bed is almost completely disconnected from the truck. The only remaining connections are to the running boards. I'll climb under the truck in a couple of days and sever those connections. Once done, I'll remove the bed. I'm thinking of turning the truck around to make reaching the cab corners with the welder a little easier. My old tires were dry rotted and one would not hold air. So rolling around on those old tires wasn't going to happen. In come the new tires and rolling is now doable. I went with 16 inch wheels and 215 70R 16 tires per the recommendation. I think that they look great! You can judge for yourself. Pics attached. First pic is of the new wheel/tire combo on the truck. The second pic is a comparison between the old 235 75R 15 and the new 215 70R 16 tires.
