Ive been working at Discount Tire Co. for about 1 year know so i get to see what fits and doesnt. I tried a 31/10.50/15 on my 88 B2 with no lift. It gave the fender wells a nice full look, i liked it. So then i turned it, and i didnt fit. It hit on the finder. Tomorrow im going to try and fit a 30/9.50/15. Everyone is saying it will fit, so lets see.
Largest tire recommended (by Discount) on stock wheels and no lift is 30x9.50-15. Every chart I've seen says with 4 1/2" lift the largest you can fit under is 31x10.50-15. Anything larger than that requires modification / more body or suspension lift. I'm still in the process of planning out my buildup, I'd -like- to get 33x10.50-15s under mine. We'll see.

I've got 35x12.50x15 BFG AT/s on mine...but i also have 4 inch suspension and 3 inch body lift. 31's would fit fine with just a body lift..if not cut the fenders..there might be a llittle rubbing on the radius arms.

05 F250 Superduty Diesel--tows the BII to the trails
I run 235/75R15's on my '87. The tires would rub on the sway bar (if the sway bar was installed) and, occasionally it hits the passenger fender if everything is just right. Technical data I have for Cooper tires suggests that a 30x9.5 is less than 0.5 in taller, so I wouldn't be surprised if it fits acceptably.
BTW, I've put the 31x10.5R15's from my Explorer onto my BII, and they are driveable, but they rub quite a bit if the suspension flexes or when turning sharp.

My winter tires are 30x9.5x15 MT Baja Belted and I have no problem with rub either when bouncing or turning from steering lock L to R. The bonus with that is the excellent turning radius is maintained and that has got me out of some pretty tight places. Good Luck!
