Based on the above examples, I decided that I liked a combination of #4 and #6 so I decided to go with a Cragar Series 397 Soft 8 17x8 et 0 steel wheel in black so the tire would poke out 46mm more than stock. This makes the tire look wider than it really is and the 17x8 wheel wouldn't have any problem with fitment.

I read in several places that a 31" tire would fit on the stock X5 suspension without rubbing (and no lift). This helped me to decide that the tire size would be 265/70/17.

Then I had to make a choice about tire makes. After looking at a lot of tires, it came down to the BF Goodrich TA K02 vs the General Grabber ATX. Back in the day, I had owned several sets of the original BFG TA All-Terrains and they were top notch.

However, the Grabber ATX had some great reviews and I really liked the look of the aggressive sidewall and they were quite a bit cheaper than the K02's, so I decided to go with the Grabber ATX.
