How long do tyres actually last? And do they have a use-by date?

There is no set guideline on how many kilometres your tyres should last, as each brand, type, and size has a different construction and with it, tread wear. Often, tyres will last anywhere between 10,000km and 50,000km. If your tyres are wearing out quicker than 10,000km, then you may have an alignment issue, and your car should be booked in for a steering alignment pronto.
