Different tires will have English letters on the sidewall to indicate the speed rating of the tire. It represents the certified speed rating of the tire from 4.8 km/h to 300 km/h. The following is an introduction to relevant knowledge about tires: 1. Definition: The tire speed rating refers to the maximum speed at which the tire can carry the specified load under specified conditions. Generally, different tires will have English letters on the sidewall to indicate the speed rating. 2. Tire selection: Many internationally renowned car brands use American Goodyear tires, the advantage being excellent tire grip, but the disadvantage is that the tires are not wear-resistant and are expensive. For Chinese road conditions, French Michelin tires are quite good, with soft rubber texture, making them very noise-resistant, but the disadvantage is that the tires are not wear-resistant and may not withstand bumpy roads.

The speed rating marked on tires is actually quite important. As an experienced driver with over a decade behind the wheel, those letters on the tire sidewall indicate the maximum safe speed. For example, H represents 210 km/h, while V stands for 240 km/h. Common models vary - compact cars mostly use H or V, while sports cars may go up to W or Y. I remember once driving at 220 km/h on the highway with V-rated tires, and it felt rock-solid. If I had used lower-rated tires, it could have been dangerous. My advice is to always check your vehicle's original standard code when selecting tires and avoid downgrading to lower speed ratings. Exceeding speed limits on highways with underrated tires increases the risk of blowouts, and skidding could be disastrous. Also, regularly inspect your tires for wear and aging to ensure these speed rating letters remain clearly visible.

The speed rating is indicated by those capital letters on the sidewall of the tire, such as S representing 180 km/h, T for 190, H for 210, and V for 240. As an ordinary car owner, I always pay attention to this when getting new tires because the speed rating set by the manufacturer matches the vehicle's performance. When checking it myself, I squat down to look at the tire edge, find a string of alphanumeric characters, and the location is easy to spot. If the letter is V or higher, it means safer high-speed driving; but if the tire is aged or the rating is too low, like buying cheap tires marked only with an S rating, driving too fast can cause the tire to overheat and burst. So I suggest not going for the cheapest option when buying tires, but choosing the standard matching rating. For daily driving, 180 km/h is sufficient—safety first.

Tire speed ratings are indicated by letters, such as H-rated for 210 km/h. Exceeding this limit is dangerous. From a driver's safety perspective: lower-rated tires significantly increase the risk of blowouts at high speeds, potentially leading to loss of control and accidents. When selecting tires, check the letter rating to ensure compatibility with your vehicle's speed capabilities.
