The most common reasons tyres fail — pressure, load, impact damage, alignment and age — and how to spot the early signs.
Tyre failure rarely comes from nowhere — it's usually the result of one or more ordinary, avoidable factors building up over time. Here's what actually causes it, and what to watch for.
Under-inflation is one of the most common causes of tyre failure. Running low on air lets a tyre flex more than it's built for, generating heat that weakens its structure over time. Over-inflation causes its own problems, wearing the centre of the tread faster than the edges. A monthly check against your vehicle's recommended pressure catches most of this early.
Every tyre is rated to carry a maximum load, and consistently exceeding that — a heavily loaded car or van, for example — adds strain that shows up as faster wear, overheating and a higher risk of failure. Your vehicle's manual has the load limits that apply to your specific vehicle.
Potholes, kerbs and general road debris can damage a tyre's structure in ways that aren't always obvious straight away. A sharp impact can weaken the sidewall or belt even when the tyre still looks fine afterwards, which is why it's worth having a tyre checked after a hard hit rather than assuming it's fine.
Cuts, bulges and cracking are all warning signs. Sidewall damage in particular isn't repairable — it needs a replacement rather than a patch, since the sidewall flexes constantly and any weakness there is a genuine safety risk.
Poor wheel alignment or worn suspension components cause uneven wear, often concentrated on one edge of the tyre. Left unchecked, this shortens a tyre's working life considerably and can affect handling and braking too.
Rubber changes over time regardless of mileage, so an older tyre can be due attention even with plenty of visible tread left. Cracking, perishing or a change in the rubber's texture are worth checking for alongside tread depth.
