My wife reminded me that I have tires that are like new that I removed from my Mustang before I sold it in our shed (To much Chemotherapy over the years makes you forget) .... They are Cooper RS3A in size 255/40/19 with less than 5,000 miles on them. Here is the issue I am facing the Lincoln MKZ size is 245/40/19 and the Coopers are 255/40/19 will they fit without rubbing and second will going to a slightly wider size void my powertrain warranty?
