I have a stock suspension 1999 F250 Super Duty Currently running 16X8 wheels and 285-75-16 tires. This is about as large of a tire and 16X8 wheel combo you can go stock without rub (very close to hitting the bumper). I would like to go to a 16X10 wheel for a deep disk look (Specifically Mickey Thompson Classic Locks).

If I stay stock what is the largest tire I can use with a MT 16X10 wheel without rub?

If I install a 2.5 levelling kit what is the largest tire I can use on a MT 16X10 wheel?
Thanks
DD

 

You should be able to run a 33x12.5 without any lift, not sure you could go any bigger with the leveling kit.
