UK law requires your vehicle to be fitted with the correct type and size of tyre for your vehicle type and for the purpose it is being used. This means fitting the correct tyres and ensuring that they are inflated to the manufacturer’s recommended pressure.
The legal minimum depth of the tread on your tyres is 1.6mm, across the central ¾ of the tread around the complete circumference of the tyre. (see below)
For safety, we strongly recommend that you replace your tyres before the legal limit is reached. Many vehicle manufacturers recommend replacing at 3mm. In wet weather, travelling at 50 mph with 1.6mm of tread, it takes an extra car length (8 metres) to stop than if your tread was 3mm.
It is also a legal requirement to ensure that tyres of different construction types are not not mixed on the same axle (the two main tyre types are radial and cross-ply). Please ask Roadwheel to check your tyres if you are unsure.
Mixing brands and patterns of the same construction type is permissible depending on the vehicle type and manufacturers recommendation. Check your vehicle’s handbook, or ask Roadwheel to look this up for you.
Regularly checking your tyres can help you to avoid 3 penalty point and a £2,500 fine (per tyre) for having tyres worn beyond the legal minimum limit on your vehicle
