The speed rating doesn’t imply the vehicle can drive that speed, but the tires are capable of supporting the car at that speed. For example, H falls between U and V, with the common perception that H stood for "high performance" at one time. Besides, you can also encounter H and T tires on the market. Each tire is specifically certified to perform to certain speeds. The DH7 center tread is designed for straight-line stability for long highway driving. A speed rating is an often-overlooked metric, but it is also a crucial one when it comes to high-performance tires. The speed symbol located on your tire indicates the maximum speed capability of the tire when properly loaded and inflated. Speed Rating Max MPH Max KMH; A1: 3 mph: 5 km/h: A2: 6 mph: 10 km/h: A3: 9 mph: 15 km/h: A4: 12 mph: 20 km/h: A5: 16 mph: 25 km/h: A6: 19 mph: 30 km/h. Tyre speed ratings are typically represented by a letter code that appears after the tyre size. N — Up to 87 mph. K: 110 kph 68 mph. The tyre load index and speed rating make up the tyre service description which is a standardized number located next to the size on the sidewall of the tyre. Beyond that, the tire's performance, particularly its heat dissipation, could be compromised. Typically, the further along you go in the alphabet, the higher the speed rating. At one time, the maximum speed a tire could have, aVa, was a maximum of 240 km/h (149 mph) or more. Speed ratings are given letters, and each letter represents a speed between 75-186 mph. Some tires have speed ratings of W, 168 mph and Y, 186 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; and V , 149 mph. In earlier incarnations of the speed rating system, “H” stood for “high performance,” which is why it maintains an unusual position in the speed rating spectrum today.

The ‘103’ here signifies a load index, meaning that this tire can comfortably support up to 875 kg. 107t vs 107h: Again, both these tires can carry a load of 975 kg, but their speed ratings differ. However, H and V also have obvious differences that you need to consider. It is important to buy tire replacements with the.
