New Michelin tire improves as it ages

Michelin Premier A/S tire tested during wet cornering

We don’t often cover tires, but a new model from Michelin, Premier A/S with EverGrip, has us at least a little curious. That’s because the French tire maker claims they’re not just new tires, but offer “truly revolutionary advancements in tire technology” that are “…able to break the traditional paradigm.”

That somewhat hyperbolic statement could have some substance behind it, though, because the company’s latest black rubber hoops have been engineered in a brand-new way to fight the bugbear of all tires: a steep loss in performance as they wear, a condition that’s especially pronounced in wet conditions. Two of the enablers are ingredients in the rubber compound, one being “extreme amounts” of silica to enhance road adhesion, the other being sunflower oil to maintain the tire’s flexibility and grip in cold weather. A new way of laying the rubber strands means the silica and sunflower get more evenly distributed throughout the tire.

One of the mechanical innovations is a groove design that gets wider as the tire wears down. As the depth of a tread channel decreases, which traditionally means a decrease in its ability to drive water away from the contact patch, the channel gets wider to make up for it. Furthermore, another set of more than 150 grooves beneath the outer layers are revealed as the tire wears, helping to keep wet-weather grip near brand-new-tire levels.

Michelin says a worn Premier A/S with EverGrip brings a car to a stop in a shorter distance “than a leading competitor’s brand-new tires.” The new treads go on sale in the spring in 32 sizes initially and come with a limited 100,000 km or 60,000-mile warranty. Still interested? You can find out more about them in the press release below.
