There’s no getting away from it – tyres are expensive. The growth in sizes in recent years has seen replacement costs rise significantly, so now, owners of even basic family cars can easily pay £100 a corner. A new set of tyres is often a distress purchase, with drivers needing to make a decision quickly as their car has a puncture, for example. And as Auto Express’s inbox and postbag can testify, wear is a key factor in their choice.

The trouble is, when responding to readers’ queries, it’s impossible for us to provide an accurate idea of how long a particular make and model of tyre should last.
