This is a new tire which will be launching in the new few months. Some sizes may already be available, but a full launch (I believe) with a wide range of sizes will be available on July 10.

This is a new tire promising better handling and braking than the popular Primacy MXV4, while still retaining most of the low noise and fuel economy characteristics. It does so with only a slight reduction in treadlife-- 55,000 mile warranty for the Primacy MXM4 vs. 60,000 mile warranty for the Primacy MXV4.
I had called Michelin's Tech Line to ask about tire options for the Altima, and the rep suggested that I wait for these new Primacy MXM4s if I was able to. That is how I found out about these new tires.
