Spanish Tyre Law

Tyres are considered amongst the most crucial safety elements of a vehicle, as they maintain contact with the road at all times, we hope, and Spanish tyre law is quite clear, your vehicle must be fitted with the correct type and size of tyre for the vehicle type you are driving and for the purpose it is being used. This means fitting the right tyres and for safety ensuring that they are inflated to the manufacturer’s recommended pressure.
If your tyres are not the same as those listed on your ITV card, your vehicle will fail the mandatory inspection, so it is worth checking this before you go for the test.
The legal limit in Spain for minimum depth of the tread on your tyres is 1.6 millimetres, across the central ¾ of the tread around the complete circumference of the tyre.
If you examine the tyres, you will see something called the “principal grooves”, the wide grooves in the tyre tread which have the tread-depth indicators located inside them. These indicators can be used as a guide to check the tread on your tyres.
For safety reasons it is recommended that you replace your tyres before the legal limit is reached. Many vehicle manufacturers recommend replacing at 3 millimetres. At 1.6 millimetres in wet weather it takes an extra two car lengths (8 metres) to stop at 50 mph than if your tread was 3 millimetres.
A regular check of your tyres can help you to avoid 200 euro / each wheel in fines for having tyres worn beyond the legal minimum limit on your vehicle.
