Michelin PRIMACY MXM4 RUN FLAT

It is important to get a good price for these great tires because the only problem is that they wear quickly. I purchased 4 new Primacy tires in June 2013. I drive 4 winter tires (on separate rims). In the 23 months the tires have been on my Buick, I have driven them 29,468 kilometers. The tread depth is now between 4 and 6 MM. They are getting a little "skittish" in wet weather. I have just bought 4 new tires form Quattro and I will replace at least two right away and the other two next spring. The "handling" of the Buick, a big heavy car, has greatly improved with these tires. The are also quiet and look great. I have found Quattro provides good service and great prices. The original tires listed for $359 in 2013 and I got them for $294 plus tax from my dealer. The current tires, including shipping cost $264 from Quattro! I heard rumours that Michelin was going to stop the manufacture of the MXM4 so that is why I bought four tires, now. Hope the rumours are not true.
