I am gonna try to put on a 2.5" level kit on a 2006 4x2 and want to put 305 tires on 17x9 wheels...will this work? If not 285/70/17..im wonderin more about how wide a wheel i can put on it...considering usually 3" of lift is obtained by this level kit...thanks

 

If the wheels have 5 inches of backspacing (or more), you should be able to fit 305/65-17's (33x12.50)
