If you go to 16" rims, the advantage would be that more brands offer tall, skinny tires. For 15" rims, BFG & some bias tires are about it. A good size you might want to consider for 16" rims would be 255/85R16. These are right at 10" wide & the same height as a 33. 7.50R16 is another good size as mentioned, but will stand about an inch shorter than the 255/85's & obviously about 2.5" narrower. I'm an awful big fan of the Cooper STT radials, but will NOT recommend these tires in the 255/85R16 size. The reason is that for some strange reason, this size (and the 235/85) have a raised center bar between the center-most lugs (perhaps because of the load rating???). What happens is that when these reach 50% tread, the center lugs blend together & only the outers are still functional. I had a set of these on my pickup & had to discard them at 32,000 miles because of this. That's about 15,000 less than I ever got out of this style tire on any of my other full-size trucks. But, when they were new
BOY did they ever work nicely. On an elk hunting trip in CO, I went through some spots where guys on shorter tires WITH CHAINS were busy digging themselves out. They were too embarrassed to let me pull them out! BFG makes the 255/85 size as well as a number of other manufacturers & generally speaking, this size is considerbly cheaper than the same-height (but slightly wider) 285/75R16. I'd look at some different brands & see what you want. If you go with the BFG, I'd get the 15" rims & the 33X9.50's unless you can find a deal on some cheap 16" rims. If you have a CJ (can't remember exactly what you have), you might be able to get some factory 16's from a late-model Dodge in your wheel pattern (5 on 5.5") pretty cheaply.
