What is the warranty on those winter / snow tires? The answer is 40,000 miles if you're looking at the Michelin Latitude X-Ice Xi2 (shown top left) or the Michelin X-Ice Xi2 (shown bottom left). Michelin is the first manufacturer of a winter tire available at Tire Rack to add a mileage warranty.
If you have seen our tire survey results on the Michelin X-Ice Xi2, it does rank the highest in treadlife. The Latitude X-Ice Xi2 is new and we do not have enough review miles just yet to see any trends.
Treadlife warranties are a great deal for consumers, but the tires can only be in use from September until the end of April. Also, the manufacturer does require uniform wear down to 2/32 of tread. Tire Rack recommends replacing winter tires wore down to 5/32 tread wear as they are not as effective with less tread.
I would recommend buying these tires for their good blend of dry road handling, winter traction, fuel efficient and long wear characteristics than just for the mileage warranty. As I recommend when comparing tires based on fuel economy and using the fuel economy information as a tie breaker between the two — if you can't decide between two winter tires use the treadlife warranty on the Michelin X-Ice Xi2 or Latitude X-Ice Xi2 as a tie breaker.
