Ask a driver what warranty their tires carry and you will usually get one confident answer: a number. “They’re warrantied for 100,000 kilometres.” Here is the part nobody explains at the counter: there is no single tire warranty. Your tires carry several separate warranties at once, each with its own rules, its own expiry, and its own fine print — and the big number is almost always the least generous of them. This guide separates them, so you know what you actually bought.

1. Workmanship and materials: the defect warranty

Every name-brand tire sold in Canada carries a workmanship and materials warranty. It covers defects from the factory — a construction flaw, a bad splice, a tire that will not balance or run true. If a defect shows up early, typically within the first 2/32 of an inch of tread wear or the first year, the tire is replaced free, including a separate uniformity promise for ride disturbance and vibration. After that early window, a confirmed defect is handled on a prorated basis until the tread reaches 2/32 of an inch — 1.6 mm, the legal worn-out point.

What it does not cover matters just as much: normal wear, impact damage, puncture damage, and wear caused by running underinflated are not defects. A sidewall bulge from a pothole is damage, not a warranty claim — which is exactly why the third warranty on this list exists.

2. The treadwear warranty: the big number, explained honestly

The mileage warranty is the one in the advertising: 80,000 km, 100,000 km, sometimes more. It promises that the tread will last at least that long under proper use. If the tire wears evenly down to the wear bars before the promised distance, the manufacturer owes you something — but not a free tire. Treadwear claims are prorated. Wear out a 100,000 km tire at 50,000 km and you receive roughly a 50 percent credit toward a replacement, and you still pay for mounting, balancing, the tire levy, and tax. The warranty softens the bill; it rarely erases it.

It is also conditional. To honour a treadwear claim, manufacturers expect the maintenance basics to have happened: rotations on schedule — typically every 8,000 to 13,000 km — correct inflation, and a vehicle in proper alignment. Uneven wear from a bad alignment is not the tire’s fault, and the claim will be reduced or denied. Keep your rotation invoices. No records is the single most common reason a legitimate claim dies.

3. The winter tire exception almost nobody mentions

Here is the gap that surprises Canadian drivers every fall: most winter tires carry no treadwear warranty at all. Winter rubber is a soft, cold-weather compound built for grip below 7°C, and it is used seasonally — so manufacturers largely exclude winter lines from mileage promises. Your winters are still covered for workmanship and materials defects, and some carry road hazard help, but if a winter tire wears out in three seasons, there is no mileage claim to file. When you compare winter tires, compare tread depth, compound, and test results — not a warranty number that is not there.

4. Road hazard: the pothole and nail warranty

Road hazard coverage pays when the road damages the tire — a nail in the sidewall, a pothole impact break, a cut that cannot be safely repaired. Some manufacturers include a limited version free on certain models, typically covering the first year or the first 2/32 of wear; a few go further, such as Falken covering up to 3/32 of wear or two years on select lines. Beyond that, road hazard is usually a retailer protection plan sold at purchase. Neither version is automatic: if road hazard matters to you — and on GTA roads under constant construction, it should — confirm in writing whether your tires carry it before you need it.

5. The tires your new car came on are different

Original-equipment tires — the set fitted at the factory — generally carry the defect warranty but no treadwear mileage promise from the tire manufacturer. This catches EV owners hardest. Electric cars are heavy and deliver instant torque, so factory tires wear faster than most drivers expect, and when they are done at 45,000 km there is usually no mileage claim behind them. If long tread life matters, it is negotiated at replacement time, when you can choose a tire that actually carries the warranty.

6. Trial periods, and the fine print that voids everything

Many major brands add a ride-and-try trial — commonly 30 to 45 days — during which a set you genuinely dislike can be exchanged. It is the most underused promise in the business. Against that, the void list is strict: driving underinflated, skipped rotations without records, misalignment wear, using the tire outside its application, and cosmetic damage, which is never covered at any age. Staggered fitments — wider rears that cannot rotate front to back — commonly see the mileage warranty cut in half or removed entirely, because the rotation the warranty depends on is impossible.

How a claim actually works

A claim starts with a measurement, not an argument. The tire is inspected, tread depth is recorded at several points, service records are reviewed, and the wear pattern is read like a report card — even wear points to a warranty conversation, cupped or one-sided wear points to the car. If the claim is accepted, the credit is calculated from the unused portion of the promised life, applied to a replacement tire of the same family. The process is fair when the records are in order, and frustrating when they are not — which is why the cheapest warranty protection you own is a folder with your rotation invoices in it.

Frequently asked questions

Do winter tires have a treadwear warranty?
Usually not. Most winter tires are excluded from mileage warranties because of their soft seasonal compounds. They still carry full workmanship and materials coverage against defects.

If my tire wears out early, do I get a free replacement?
Almost never. Treadwear claims pay a prorated credit based on the life you did not get — wear out a 100,000 km tire at 50,000 km and expect about half the tire’s value in credit, with installation, levy and tax still yours to pay.

Do I really need rotation records to make a claim?
Yes. Manufacturers condition treadwear coverage on scheduled rotations, proper inflation and sound alignment. Documented rotations every 8,000 to 13,000 km are the difference between an approved claim and a denied one.

Are the tires that came on my new car covered by a mileage warranty?
Generally no. Factory-fitted tires carry defect coverage, but treadwear mileage warranties usually apply to replacement tires you buy, not the original set — one reason EV factory tires wearing out early comes with no claim attached.

Buy the warranty you will actually use

A tire warranty is not one promise; it is a stack of them, and they are not equal. Defect coverage comes with every name-brand tire. The mileage number is a prorated credit with homework attached. Winter tires largely opt out of mileage promises altogether, and road hazard — the coverage GTA drivers use most — is the one most often missing. Read the stack before you buy, keep your records after you buy, and the warranty becomes what it should be: a real safety net instead of a sales line.
