Whether original equipment (O.E.) tires come with a mileage warranty depends on the tire manufacturer and the specific tire model. O.E. tires are the tires that come installed on a vehicle when it is brand new from the factory. These tires are often selected by the vehicle manufacturer to meet specific performance, safety, and fuel efficiency criteria.

Many tire manufacturers do offer mileage warranties on their tires, but the terms and conditions can vary widely. The mileage warranty typically guarantees that the tires will last for a certain number of miles before they wear out, and if they wear out prematurely, the manufacturer may offer a pro-rated replacement or refund.

To find out if your O.E. tires come with a mileage warranty, you should check the documentation that came with your vehicle or contact the vehicle manufacturer's customer support. Additionally, you can check the tire manufacturer's website or contact them directly for information about warranties on specific tire models.

Keep in mind that mileage warranties usually require proper tire maintenance, including regular rotations and maintaining the correct tire pressure. Failure to follow recommended maintenance procedures could void the warranty.
