as work on my truck progresses, im going to order tires before shipping rates are reflected in the increase of fuel cost. I really want this truck to be almost expedition styled- meaning no real rock crawling, but similiar to the functionality of the Turtle Expedition or the Earth Roamer. (two ends of the scale). Turtle is functionality over Luxury- Earth Roamer is like a yhat on wheels. Turtle has and still uses ALCOA hot forged aluminum one-piece wheels. Tires were BFGoodrich 255/85R/16/D Mud Terrains. They have used Ford f350's. Earth Roamer uses f450 and f550's. They have run a variety of wheels and tires, from the 19.5's to 16" BFG muds like turtle. Currently they are running Michelin XZL 16x9's. which are 36.4" tall. the truck that I am building the base on is a 92 k2500. Yes, it is IFS. What is the largest tire I can fit, trimming away the fenders? They must still be 16" in diameter.
