As the only component on your vehicle that actually makes contact with the road surface, tyres are critical for safety when driving.How do you read the markings on a tyre?The markings on a tyre indicate its size, load index and speed rating. A typical tyre marking looks like this - 205/55 R16 W 91. What is the UK legal tyre limit?The minimum tread depth required by law in the UK is 1.6mm. This applies to the central three-quarters of the tyre’s width and its entire circumference. Many car manufacturers, however, advise changing your tyres once the tread is down to 3mm to be on the safe side. What are tyre speed ratings?A tyre speed rating is the maximum speed a particular tyre is legally approved for. The rating is represented by a letter displayed on the tyre sidewall. It will always be the last letter in the sequence.
