Speed Rating
The speed rating is a letter on the tyre that shows the maximum speed it is designed for.
What is Speed Rating?
Common ratings are T (190 km/h), H (210 km/h), V (240 km/h) and W (270 km/h). Winter tyres may have a lower rating if a reminder sticker is used. Other common letters are Q (160 km/h), R (170 km/h), S (180 km/h) and Y (300 km/h).
How it works
The tyre is tested to run safely up to this speed at its rated load.
Why it matters for your car
Using a lower rating than specified can be illegal and reduce safety. The speed rating also reflects the tyre's construction and heat resistance, not just its top speed.
