When I bought my bump in 2009, I wanted to go immediately to all stock configuration. I put the closest thing(radial tire) to the original bias ply that I could find within reason. I put a set of 215/75/15 Michelin Tires on the original rims. They were much better than the dry rotted tires that had been on the truck for the past 20-something years, but I soon realized I went on the "small" side with my tires. Wanting to get my money's worth out of them, I drove on those Michelins for three years while researching and saving up for another set. I got used to those small, original size tires over time. But, this year I found a local deal on craigslist that was too good to refuse. I bought a set of 4 BF Goodrich 31x10.5x15 All Terrain tires mounted and balanced for $455. They're only a year or two old and have 75%+ tread remaining. I am really glad I bought these tires for several reasons. First, they look really good on my old bump(which use to be a Texas ranch truck). Second, they ride better(not as hard). Third, the traction off road is a whole lot better. I do a lot of landscaping and odd jobs where I'm needing to haul equipment back in the woods and off road. These tires have increased my bump's off road capability dramatically. I drove through a sand pit last week where I've would've certainly gotten stuck before with the old tires. Overall, so far, this is one of the best purchases I've made for my bump. Wish I had made this tire decision three years ago, but I enjoyed my stock size tires(which I still have). I forgot to mention, two years ago I bought a second set of original Ford 15" truck rims, had them sandblasted and repainted. So, I have 2 sets of tires and wheels as of right now. Figure, I'd hold onto the Michelins in case I buy another old truck that needs a decent set of wheels/tires or might consider selling them(they still have lots of life left in them). The 31" tires are as big as I would go without doing a lift(which is something I don't care to do). Any bigger would be too big. These are just right for the size of my truck.
Here's a picture of what my bump looks like now with the 31" tires:




Here's what it looked like with the stock size Michelin 215/75/15 tires I had on it:



Hope this helps anyone who might have tire questions or thoughts.
