Tire warranty guide

What does a tire warranty cover?

Tire warranties typically cover manufacturing defects in materials and workmanship — bubbles, tread separation, or sidewall failures caused by production errors. They do not cover road hazard damage (punctures, cuts, impact damage), wear from under-inflation, incorrect fitment, racing use, overloading, or damage caused during mounting. Most passenger car tire manufacturers offer a workmanship and materials warranty for the life of the tread (or 4–6 years), and some offer a separate mileage-based tread wear warranty (60,000–80,000 km) for eligible touring tires. Proof of correct fitment, rotation history, and inflation maintenance may be required for tread wear warranty claims.

Types of tire warranty

Warranty type	What is covered	What is not covered	Duration
Manufacturing defect warranty	Bubbles or bulges caused by production errors; tread separation from internal structure; sidewall failure without external damage; bead damage from factory	Road hazard damage; punctures; impact breaks; kerb damage	Life of original tread depth or 4–6 years from manufacture date, whichever comes first
Tread wear warranty (mileage)	Premature tread wear — tire reaching legal minimum before the warranted mileage (typically 60,000–80,000 km for touring tires)	Wear from incorrect inflation, misalignment, no rotation, aggressive driving, or overloading. Most warranties are pro-rated.	Set mileage from date of purchase (65,000 km / 40,000 miles is typical for mid-range touring)
Road hazard warranty (add-on, often retailer-only)	Punctures; impact breaks; pothole damage; sidewall cuts — causes of damage that are not manufacturing defects	Run-flat tire driven beyond 80 km at deflated pressure; valve stem damage; wheel damage	Typically 1–3 years from purchase; offered by retailers not manufacturers
Uniformity / first 30-day warranty	Vibration and pulling caused by tire non-uniformity detected within first 30 days / first 1,600 km	Vibration caused by wheel balance issues, alignment, or suspension	30 days or first 1,600 km

What voids a tire warranty

Void condition	Why it voids the warranty
Incorrect inflation	Operating at more than 20% below or significantly above the placard pressure. Under-inflation creates excess sidewall flex and heat, accelerating structural fatigue. Most claims denied if pressure records show chronic under-inflation.
Incorrect fitment	Tire size or load index not matching vehicle OE specification, or XL tire fitted without using XL pressure. Warranty void if tire was mounted on incorrect rim width (outside ETRTO permitted range).
Racing or track use	Any use on a closed circuit or motorsport event voids manufacturer warranty. Speed rating exceedance also voids warranty.
Overloading	Operating above the tire load index rating at its inflation pressure. Common on commercial vehicles — warranty void if vehicle regularly exceeded its GVWR.
No rotation (tread wear warranty)	Tread wear warranties typically require documented tire rotation every 10,000–12,000 km. Failure to rotate voids the wear warranty — but not the manufacturing defect warranty.
Damage caused during mounting	Bead damage from improper tire machine use, valve damage during fitting, or tire damage from a split rim — these are installer liability, not manufacturer.
Tire modified or retreaded	Retreading, regrooving, or drilling voids all warranties.
Road hazard damage	Punctures, cuts, impact breaks, and pothole damage are excluded from the standard manufacturing warranty. Require a separate road hazard cover policy (see above).

How pro-rata tread wear warranties work

A pro-rata warranty does not give you a free replacement tire if it wears out prematurely. It gives you a credit proportional to the unused portion of the warranted mileage, applied toward the purchase of a replacement. The higher the mileage at failure, the smaller the credit.

Example scenario	Pro-rata calculation	Claim value
Tire warranted for 70,000 km; fails at 40,000 km	40,000 / 70,000 = 57.1% used. Remaining = 42.9% of purchase price.	Credit of ~42.9% toward replacement tire (not cash; typically applied at purchase of replacement)
Tire warranted for 60,000 km; fails at 55,000 km	55,000 / 60,000 = 91.7% used. Remaining = 8.3%.	Very small pro-rated credit — at this mileage the tire is nearly at end of expected life
Tire warranted for 80,000 km; fails at 10,000 km	10,000 / 80,000 = 12.5% used. Remaining = 87.5%.	High pro-rated credit — may also trigger full defect warranty investigation

Important: the pro-rata credit is typically applied at the current retail price of the replacement tire, not your original purchase price. If tire prices have risen, the credit covers a smaller fraction of the new tire cost.

Manufacturer warranty vs retailer warranty vs road hazard cover

These are three different things and often confused:

Manufacturer warranty — covers production defects. Registered and honoured by the tire manufacturer, processed through the retailer. Not negotiable at point of sale.
Retailer warranty or guarantee — the retailer may offer additional coverage beyond the manufacturer warranty (e.g. 1-year road hazard, price match, free rotation). Check the specific terms — these vary by retailer and are not standardised.
Road hazard cover — optional paid add-on covering punctures, impact damage, and sidewall failures caused by road conditions. This is not a manufacturer warranty — it is an insurance-style product. Cost is typically 10–20% of tire purchase price per year.

The DOT date code and warranty expiry

Manufacturer warranties for manufacturing defects typically run from the tire's date of manufacture (the last four digits of the DOT code on the sidewall), not the purchase date. A tire manufactured in week 32 of 2022 (DOT: ...3222) manufactured 18 months before purchase may have already consumed part of its 6-year warranty period at the time of fitting.

Most manufacturers refuse warranty claims on tires manufactured more than 6 years ago, regardless of tread remaining. For the full guide to tire date codes and age limits, see our Tire age guide.

How to make a warranty claim: step by step

Document the failure — Photograph the tire: full sidewall (DOT date code visible), the failure location close-up, and overall tire condition. Note the tread depth at the failure zone.
Locate purchase records — Find your purchase receipt, fitting date, and any rotation records. Mileage at time of failure must be verifiable (odometer photo or service record).
Return to the point of purchase — Most warranties are processed through the retailer who sold the tire, not the manufacturer directly. Bring the failed tire, purchase receipt, and vehicle details.
Retailer inspection — The retailer will inspect the tire and assess whether the failure is consistent with a manufacturing defect or external damage. Disputed cases may be sent to the manufacturer.
Manufacturer assessment — If escalated, a manufacturer representative or independent laboratory inspects the tire. This process typically takes 2–6 weeks.
Claim resolution — If the defect is confirmed: replacement tire, pro-rated credit, or refund depending on the warranty type. If denied: retailer provides written reason; you can escalate to the national consumer protection authority.
