I ran 12.50/33 BFG A/Ts on 10" wheels on my '90 Blazer. I did go to the spring shop and get it leveled up by arching and adding a leaf,which gave it 1-2". I didn't really "wheel" it and they cleared fine. 8" wheels would really help give better clearance. BFG also makes a 9.50/33.
Here it is all stock with 11.50/32s:
