Tire Warranties Decoded: What's Actually Covered (and What Isn't)

Tire warranties are some of the most misunderstood paperwork in the car world. People assume they're covered for anything, then find out a pothole isn't included. Here's what a tire warranty actually covers, in plain English.

The first thing to know: there isn't one tire warranty. There are usually several, and they cover different things.

The short version

• A treadwear (mileage) warranty covers premature, even wear — and it's prorated.
• A workmanship/materials warranty covers manufacturing defects, not road damage.
• A road hazard warranty (often optional) covers punctures and impact damage.
• Most warranties require proof of rotations and correct pressure to stay valid.

Treadwear (mileage) warranty

A tire rated for, say, 100,000 km is warrantied to wear evenly to roughly that figure. If it wears out early and evenly, you get a prorated credit based on how much tread life you used. The catch: it only covers even wear, and you usually need rotation records to make a claim. Uneven wear from alignment or pressure problems isn't covered. Keeping up with tire rotation is what protects this warranty.

Workmanship and materials warranty

This covers manufacturing defects — a tire that fails because of how it was built, not because you hit something. It typically runs for a set number of years or down to a certain tread depth, and is prorated as the tire wears. Road damage is not a defect, so it isn't covered here.

Road hazard warranty

This is the one most Calgary drivers actually want, because it covers punctures, cuts, and impact damage from potholes and debris. It's often a separate, optional add-on. If the damage is a repairable puncture, it's fixed; if it isn't, you get a credit toward a replacement. We explain our road hazard protection in plain terms.

What's usually not covered

• Pothole or impact damage without road hazard coverage.
• Wear from running under- or over-inflated.
• Wear caused by misalignment — here's the difference between alignment, rotation, and balancing.
• Racing or hard off-road abuse.
• Cosmetic curb scuffs.

How to keep your warranty valid

Rotate on schedule and keep the receipts, maintain the correct pressure, fix alignment issues promptly, and register the tires if the manufacturer requires it. Most denied claims come down to missing rotation records or chronic under-inflation. For context on how long a set should last, see how long tires last in Calgary.

Frequently asked questions

Does a tire warranty cover pothole damage?

Only if you have road hazard coverage. Standard treadwear and workmanship warranties don't cover impact damage from potholes or debris.

What is a prorated tire warranty?

It means you get credit based on the unused tread, not a free replacement. If a tire fails halfway through its rated life, you'd get roughly half the value toward a new one.

Do I need rotation records to claim a warranty?

Usually yes. Treadwear warranties typically require proof that the tires were rotated on schedule, so keep your receipts.

What voids a tire warranty?

Common reasons are improper inflation, ignored alignment problems, racing or off-road abuse, and missing rotation records.

Is road hazard coverage worth it in Calgary?

For pothole season and construction-zone debris, it often is. A single pothole that ruins a tire can cost more than the coverage.
