Hello,

Thank you for your question.

According to the law in the UK it's not forbidden to fit asymmetrical tyres on the front and directional tyres on the rear. However, we strongly discourage it. The tyres behaves in different ways and your vehicle might not be as stable as when the same tyres are fitted, which could be very dangerous.

Happy driving,
