What is the difference between tire speed ratings V and H?

[VonMila]

The difference between tire speed ratings V and H lies in their maximum speed capabilities. A tire with an H rating has a maximum speed of 210 km/h, while a V-rated tire can handle up to 240 km/h. In terms of top speed performance, V-rated tires outperform H-rated ones, and consequently, V-rated tires are also more expensive than H-rated ones. Higher tire speed ratings indicate better heat resistance and stronger grip during vehicle cornering. Common speed rating letters for family car tires include Q, R, S, T, U, H, V, W, and Y. The Y rating represents the highest speed grade, capable of reaching speeds up to 300 kilometers per hour. Tires with higher speed ratings generally have lower durability compared to those with lower speed ratings. This is primarily because higher-speed-rated tires tend to have softer compounds, making them less resistant to wear. It's important to note that higher tire speed ratings aren't always better. While tires with letters further in the alphabet generally indicate better performance, they also come with higher price tags.
