I had a 93 stock F-150 with 31 BFG's and the 33 would fit but you will rub in the front while turning. As far as lifts, take your pick....

I have seen 33 12.50 15 tires on one. The guy said he had to move the front bumber forward though. 1 inch I think. But 9.50s may work better, since they are narrower and will stay in the fender well better when turning.

 

I ran 32x11.50s on my 88 bronco -- same platform as the 150 I think, and it only rubbed slightly on the left radius arm at a full left turn. 33s will rub in the same place even if they are 9.50s or 12.50s. Its the height when turned that causes the rub

I ran these on 15x8 AR rims with about 1/2 inch less backspacing than the stock 15x8 steel rims.

33x12.50 Mud Kings on 15x10 Cragar Street Stars and they do rub on the radius arms.

I have a friend who was running the 33-9.50 BFG AT-KO on the factory wheel on a 94 Bronco. They cleared without rubbing, even at full flex, jumping, and turning. He is still running the tires, but I talked him into giving up, and he bought a lift.

I would definitely get a lift before tires. I think it sucks to worry about rubbing and cutting or moving fenders. Plus it looks sh!ty if the tires are too big and there is no clearance between tire and fender.
