Remember, he has a 4x2, not a 4x4. The 4x2's sit 2 inches lower. A lot depends on the wheel width and backspacing you use. With the OEM wheels or an aftermarket 8 inch wide wheel with 4.5 inches of backspacing you can fit 285/75-16's/ 185/70-17's (33x11.50) easily.
Also, a 295/75-16 and 295/70-17 are essentially 34x12.00 tires. You will need a little more lift to fit them on your leveled 4x2.
