You also need to check the tread depth, which should be at least 4mm. If you have a lower tread depth than the 4mm, you need to buy a new set of tyres. Low tread depth impacts the grip and the stability when you drive. Your braking distance will also increase making you a more dangerous driver to others as well as to yourself. It is even more important for winter tyres as they have to deal with thick snow and slush. For the summer tyres it will have a significant impact on the prevention of aquaplaning.
