* Mileage Warranty Exceptions
Split fitments - If your vehicle has tires of different sizes on the front versus the rear axles, your tires cannot be rotated as recommended. Therefore, the mileage warranty on each rear tire will cover half the number of miles as the standard mileage warranty for that particular tire line.
ZP (Zero Pressure) tires - The maximum mileage warranty for ZP tires is 30,000 miles.
Standard limited warranty on all Michelin tires
Standard Limited Warranty
All Michelin® Tires
All Michelin® tires have a Standard Manufacturer's Limited Warranty, which covers defects in workmanship and materials for the life of the original usable tread, or for 6 years from date of purchase, whichever occurs first. See warranty for details
