The minimum legal tread depth for a tyre is 1.6mm across the middle 75% of the tyre at any point. You can check this by the tyre wear indicators that you'll find within the base of the tyre tread groove.
Once the tyre tread has worn below these indicators your tyres are illegal. We recommend you act when they're down to 3mm, as by this point, the tyre is 78% worn and road-holding, acceleration and braking will already be compromised, especially in wet and wintry conditions.
Remember, when your tyres are below the legal limit this can result in a fine and penalty points on your driving license.
