Your bronco probably has 3.55:1 or 4.10.1 gear ratio in the axles. stay at the 30" tire size :example---»»» 30/10,5/r15( 235/75 /15) maybe 31 not sure

I have the same B2. But, with 373 gears. I also have a 2" suspension lift. have been wanting to go with the 31s. But i am told and have been reading the forum that that isnt the best setup to run 31s. should at least have 456s to maintain the proper performance of the little b2.
currently i have 235s on it and i will probably keep them on that way for awhile.

Welll you need 4.10's with 31's and 4.56's with 33's. But I'm running 31's on both my 84 (2.8L) and 99 (3.0L) with a little drop in performance but not really noticable with the 3.73's.
But I would say stick with 235/75R15's any bigger then that and you'll be rubbing more then likely

Check your springs out too. Most B2s have issues with spring sag just from age. You may get rub even with 30s if your leaf springs are wearing out.
