Car Tyre Speed Rating

The speed rating of a car tyre is a measure of the maximum speed that the tyre is designed to safely sustain over an extended period of time. It is indicated by a letter code that appears on the tyre's sidewall.

The speed rating system uses a letter code from A to Z, with each letter representing a specific maximum speed range in miles per hour (mph) or kilometers per hour (km/h). Here are the most common speed ratings and their corresponding maximum speeds:

S: 180 km/h (112 mph)

T: 190 km/h (118 mph)

H: 210 km/h (130 mph)

V: 240 km/h (149 mph)

W: 270 km/h (168 mph)

Y: 300 km/h (186 mph)

Z: Over 240 km/h (149 mph)

It's important to note that the speed rating is not an indication of the tyre's performance or quality, but rather a measure of the tyre's ability to safely sustain high speeds over time. Choosing a tyre with an appropriate speed rating for your vehicle is important for safety and performance. It's generally recommended to use a tyre with a speed rating that matches or exceeds the top speed of your vehicle.
