Mine has about 1" cut off the rear fender, and these are Goodyear MT/Rs, not BFG A/Ts...31x10.50 on 15x8 white wagon wheels. The other truck has a 4" lift with 34x10.50 LTB Super Swampers.
 
Yes I have 31" x 10.50 Goodyear MT/Rs on 8" wide wheels. Just be careful, like CruiserStuff said, about the rear fender if you end up flexing it. Mine is cut already so I don't have any problems there (it is also loaded with camping gear in that picture). I also don't know what the 5.5" wide rim you have will do to the tire profile. Like some of the above said, the 33x9.50 has been known to work and fit inside the wheel wells on stock height trucks, and only rub when turning. So if you still want the 33 you might look into that, and I am pretty sure BFG makes the AT in that size. There are always variables with trucks this old, but try to find one that's close to what you're looking for and give it a try and post up pictures of yours once you are done. I almost snagged some 31x10.50 BFG A/Ts for my stock steelies, but missed them by a few minutes, so unfortunately I don't have a picture that's any closer to the setup you're looking at.
 
Discount can order tires if they don't have them in stock. I had to order a set of 27x8.50 R14 BFG A/Ts for my pickup a few years ago (they don't make THOSE any more), took them about a week to get them in.

Yep, BFG still makes them:

The other problem you may run in to is that nobody will want to mount them (a 33x9.5 (6.5-8.5" rim sizes) or a 31x10.5 (7-9" rim sizes)) on a 5.5" rim. But somewhere someone does because there are plenty of FJ40/55s running around with them mounted up.
 
BFG makes a 33x9.5x15 only in an AT, not an MT anymore. There are lots of pics here with the 33x9.5x15's....you gotta search, though....I've given up enough freebies!! :) You can find people to mount anything if you look hard enough....no one has ever given me grief.
 
go for i

you could also get a set of Rancho part # RS60612 just over a bill and it will raise you 2" most people like the 9.50's fwiw :meh:
 
I would go with the 31's. My 40 has 4 inch lift springs, longer shackles in the rear and the shackle reversal in the front (another 1.5 inchs of lift) and my 33's still rub on rear. But mine are 33x12.5 too. I had 31x10.5's before the 33's and they did just fine.
 
The 33x 9.5's are narrow , but not that narrow. I think they look good. Kinda gives the truck an old school vibe.

Check out Paul's thread (post #41). He just put 33x9.5x15 with a 2.5" OME lift. I know you will not be lifting it but Paul likes the 9.5's (especially since he does not have power steering). Thought this picture would give you a good idea how 9.5's would look.
