How Long Do Tires Last? Mileage and Age Guidelines

Updated 2026-07-28

You check the tread with a coin and it still looks fine, so you figure the tires are good for another year or two. But tread depth is only half the story — a tire can look barely worn and still be unreliable if it's old enough, because the rubber stiffens and cracks with age even when there's plenty of grip left on paper. Two separate limits determine when a tire needs replacing: how many kilometers it has covered, and how many years it has spent on the car, whichever comes first.

Two limits, not one

Tire manufacturers set two separate ceilings on how long a tire should stay in service, and either one can be the deciding factor. The first is mileage: depending on the tire type, the vehicle, and how it's driven, a set of tires typically lasts somewhere between 40,000 and 80,000 km before the tread wears down to the point where wet-weather grip and stopping distance become unreliable. Softer, sportier tires tend to sit at the low end of that range because the compound favors grip over durability; all-season and touring tires built for tread life sit closer to the high end. Driving style, road surface, alignment, and how consistently the tires are kept at the correct pressure all shift the number in either direction — underinflated tires and misaligned wheels both wear the tread faster than the mileage estimate assumes. The second ceiling is age. Most tire makers recommend replacement after roughly 6 to 10 years from the manufacture date printed on the sidewall, regardless of how much tread is left, because the rubber compound stiffens and can develop small cracks as it ages, especially with sun and heat exposure. A tire that reaches either limit first is the one due for replacement — a set with plenty of tread but a decade of age on it is not safer than a younger set that has covered more distance but stayed flexible.

Signs a tire is due for replacement, regardless of what the odometer says

• Tread depth near the built-in wear bars molded into the grooves, or a failing result on a simple coin test done at several points across the tread, not only the center
• Cracks or small fissures in the sidewall rubber, often the first visible sign that the compound has started to age and stiffen
• A manufacture date on the sidewall — the four-digit code inside the DOT number, showing week and year — that puts the tire past 6 to 10 years old
• Uneven wear concentrated on one edge or down the center, which usually points to an alignment or inflation problem worth fixing before it shortens tire life further
• A new vibration at highway speed that wasn't there before, which can mean internal tire damage rather than ordinary wear

A car that barely moves still needs new tires eventually

Age-based limits catch owners of low-mileage cars off guard, because it's tempting to assume tires with plenty of tread left don't need attention yet. A car driven a few thousand kilometers a year can sit under 40,000 km for the better part of a decade, well past the point where the rubber has started to age out, even though the tread still passes a quick glance. A second car, a weekend car, or a car that sat parked for a stretch are the ones most likely to slip through — the mileage trigger never fires, so nothing prompts a check of the sidewall date. Rotating tires on a regular schedule also stretches the mileage side of the equation by evening out wear across all four positions, but it doesn't change the age clock at all. Because tire condition depends on a date as much as an odometer reading, and because a household with more than one car makes it easy to lose track of which set is closest to due, it helps to have the swap and rotation history written down somewhere other than memory. CarCare's tire management page tracks summer, winter, and all-season sets separately for each car, logs rotation history alongside the rest of the service record, and keeps swap dates on file, so checking how old a car's current tires are is a matter of opening that car's page rather than trying to recall when the last set went on.
