Michelin recommends replacing all four tires at the same time.
However if replacing only two new tires, be sure that the new tires are the same size and tire type as the current tires and that the dealer always installs the new tires on the rear axle of the vehicle.
Why should new tires be installed on the rear axle?
- New tires will provide better wet grip and evacuate water more efficiently.
- It helps reduce the potential for the vehicle to fishtail and lose stability in wet conditions
