I purchased my '13, 2.0 in February with 24k miles at a dealer auction. I had never driven an MKZ and being on the lot at an auction I didn't have the opportunity to drive this one. After purchase, when I got the car on the street, I was devastated! The ride quality from the 18" OEM Michelins (in all modes and comfort levels) was horrible and the rear end roll was borderline scary. The original tires were worn beyond what I thought a premium tire with 24K miles should be with the tread wear indicators being evident. Knowing I had to do more driving this summer than typical, I put off purchasing new tires until now. With the Michelins completely worn out (bald) at 39K miles I just installed the Pirelli Cinturato P7 Plus and I'm thrilled! The ride quality is like night and day from the Michelins and the rear end roll is GONE - 100% GONE! I now have an MKZ that rides and handles like the sport luxury machine it is!
