TWO DIFFERENT SIZE TIRES INSTALLED ON MY TRUCK FORD F250 WANTED (4 )305-70-16 INSTEAD GOT!
(2)-305-70-16 LEFT FRONT AND RIGHT REAR AND (2)-285-75-16 RIGHT FRONT AND LEFT REAR. WHAT PROBLEMS COULD HAVE HAPPENED TO TRUCK IF I DID NOT FIND MISS MATCH

Answer
Jim,

The only real difference in the tires is the tread width. The overall height of the tires is close enough as to not cause any damage.

First thing I would do is get the problem corrected and then I would find find a more competent dealer.
