When you purchase a new set of tires, you are also entitled to certain warranties that protect your investment. Understanding what these warranties cover—and what they do not—helps you make informed decisions and avoid unpleasant surprises when problems arise.
The Manufacturer’s Warranty
Every new tire comes with a manufacturer’s warranty covering defects in materials and workmanship. This warranty typically lasts for the life of the original tread depth, usually defined as the first 2/32 of an inch (about 1.6 millimeters) of wear. If a tire fails due to a manufacturing defect within this period, the manufacturer will replace it, often prorating the cost based on remaining tread depth. Covered defects include tread separation, sidewall cracking from faulty construction, and bead failures not caused by improper mounting.
The Treadwear Warranty
Many tires carry a separate treadwear warranty, expressed as a mileage guarantee. A tire rated for 80,000 kilometers, for example, promises to last that distance under normal driving conditions. If the tire wears out before reaching the stated mileage, the manufacturer provides a credit toward a new tire. The credit is prorated based on how many kilometers short the tire fell.
However, treadwear warranties come with strict conditions. You must rotate tires at the recommended intervals, maintain proper inflation pressure, and keep documentation of all service. Failure to follow these requirements often voids the warranty. Additionally, treadwear warranties typically cover only the tires themselves, not mounting, balancing, or alignment costs.
The Road Hazard Warranty
Road hazard warranties are usually offered by the retailer, not the manufacturer. They cover damage from potholes, nails, glass, and other road debris—damage that is not a manufacturing defect and therefore not covered by the manufacturer’s warranty. If a road hazard destroys a tire, the warranty replaces it, often free or at a prorated cost depending on tread depth.
Road hazard coverage is typically optional and may be included in the purchase price or sold as an add-on. For drivers in areas with poor road conditions, this coverage can pay for itself with a single incident.
What Warranties Do Not Cover
Tire warranties exclude a wide range of issues. Damage from improper inflation, overloading, misalignment, or unbalanced wheels is not covered. Damage from accidents, curbing, or intentional abuse is excluded. Tires worn unevenly due to mechanical problems are not covered. Tires used in racing or off-road competition are typically excluded. Cosmetic issues like minor blemishes that do not affect performance are also not covered.
How to Make a Claim
To file a warranty claim, you typically need the original purchase receipt, proof of tire rotations and maintenance, and the defective tire itself. Take the tire to the retailer where you purchased it or to an authorized dealer for the brand. They will inspect the tire and determine whether the damage falls under warranty coverage. If approved, you receive a replacement tire or a prorated credit toward a new one.
The Fine Print Matters
Always read the warranty documentation before purchasing. Understand the duration, coverage limits, proration terms, and maintenance requirements. Keep all receipts and service records. Register your tires with the manufacturer if required. These steps ensure that if a problem arises, you can make a successful claim and protect your investment.
