Most high-performance tires wear out quickly, but reviews say the Michelin Primacy MXV4 is an exception. With a 60,000-mile tread-wear warranty and one of the best government tread-wear ratings in its category, critics say the Primacy MXV4 is a good value despite its expensive initial price. It earns top scores from both experts and owners for its traction on dry roads, and reviews say it even handles normal snow and ice capably. However, the Primacy MXV4 gets mixed reviews for its performance on wet roads. The top-rated tire in this category, the newer Bridgestone Potenza RE970AS Pole Position (*Est. $185), beats other performance all-season tires in a recent test (especially on wet roads), but its tread-life warranty stops at 40,000 miles.

The National Highway Traffic Safety Administration is the place to find government-required ratings for tread wear, traction and heat resistance.

Aaron Gold, About.com's guide to cars, attends a Michelin press event to compare the Michelin Primacy MXV4 with the Bridgestone Turanza and Serenity Technology. Gold recommends the Primacy MXV4, but he admits that "comparing the new Michelin to just one other tire is hardly what I'd call a conclusive test," and his write-up includes few details compared with other expert reviews. (Note: ConsumerSearch is owned by About.com, but the two don't share an editorial affiliation.)
