All four of the tires in our test delivered the refined road manners we expect from Grand Touring All-Season tires, with the Michelin Primacy MXM4 doing a great job of providing comfort without feeling "sluggish." The Primacy MXM4 also delivered the quietest ride of the group and proved to be the best tire we tested in wet conditions on our track - where 90-degree street corners, lane changes and simulated expressway ramps test tires at their limit.
