87 4x4 tire size

Hi their ,hoping somebody can help me kinda new at this. I 've got a 87 1/2 ton 4x4 all stock,no lift. I would like to put 33 inch tires on without lifting the truck. I was wondering if anyone can tell me if I am going to be able to do this

 

33's will fit, but if you do any offroading, watch to make sure they don't rub the fenders.

 

I just put a new set of BF Goodrich 33x10.50 on my 87 short bed 4x4 on the stock wheels and they work great with no lift! I had 33x12.50 on wider wheels and they rubbed.
