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.

What do you guys run? With and without lift?

 

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.

 

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.

 

P78-15 Buckshots on My 90 BII, with 4 inches of suspention lift. They do rub a little when it is in a hard flex.

 

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!

 

my cousin put 33x12.50 mounted on a 15x10 rim on his 84 BII, with 3" body and 2" suspension.

 

i got 30x9.5x15 on my 88 b2 and it fits perfectly, no rubbing, good clearance
