I purchased these tires to replace the Michelin Latitude tires on my 2011 Nissan Armada SL 4x4. The tire shop initially refused to put them on the car, saying that the speed and sidewall rating were less than the OEM. I confirmed through several web sites, my Nissan dealership, and Michelin that these tires are appropriate for my Armada.
So far, I love these tires. Even my wife, who doesn't know anything about cars, commented that it feels like she is in 4 wheel drive when using them. They performed great in a 5 inch snowfall earlier in the month. They are very quiet and ride very smooth. I have owned these tires before (on my Toyota Sequoia). While expensive at about $1200 for 4 tires, the quality and tread life are worth it.
