okay so now i have put my 2 inch leveling kit on my truck i am really wanting to put some 33-12.50's on my truck. i am currently running 32-11.50's now. there is a good amount of room in between the tire and the body so could somebody possibly tell me if they would fit. and which tire is better? mickey thompson MTZ or nitto mud grappler? and i will be pairing them with 17 inch **** cepek DC-1's

 

Not sure about fitment on the 87's. You should be able to make an educated guess based on the width of your current tires and wheels and their backspacing vs. the specs on the DC wheels and the new tires.
As for the tires, both perform well, but the Mud Grapplers are extremely loud on pavement (even by MT standards) and they wear quickly. I'd go with the MTZ's.

 

Not sure about all that, but sweet truck!
