βοΈ Most drivers know the legal minimum tread depth is 1.6mm. Fewer know what's at stake if you fall below it.
You can face a fine of up to Β£2,500 and 3 penalty points per tyre, so four illegal tyres can add up fast. And grip in the wet drops off well before you reach the legal limit, which is why many safety experts recommend replacing nearer 3mm.
The 20p test is a quick one: pop a coin into the main grooves, and if you can see the outer band of the coin, your tread may be getting low.
