Many drivers, especially those who do a lot of long-distance travel, place a high value on finding the smoothest and quietest tires. The Grand Touring All-Season category combines an emphasis on luxury with good treadlife and higher speed ratings, typically H or V, that are specified for many late model vehicles. Within this category, two of the best tires are the Michelin Primacy MXV4 and the Bridgestone Turanza Serenity.
We have tested both tires, and I was impressed with their combination of pleasant handling and exceptionally smooth and quiet ride. These two options are the first that I look for in this category when making a recommendation for a customer.
The Bridgestone has a little bit sportier handling, and our customers have found that the Michelin is a little better in the snow. Either one is an excellent choice, and the decision between them often comes down to price and availability for a given size. These two are the most proven performers in the category, but there are certainly other good options available.
To view all Grand Touring All-Season tires and how they have been rated by our customers view our Tire Survey Results. Note that tires with low numbers of miles reported often take a while to find their 'true' level. Generally once there are a few million miles reported the results tend to stabilize.
