What do the tire rating letters represent?

Tire rating letters represent different speed ratings. Here are the detailed explanations: 1. Tire speed rating. The tire speed rating refers to the maximum speed at which a tire can carry a specified load under defined conditions. The speed rating W on a tire represents 270 km/h, V represents 240 km/h, H represents 210 km/h, and Y represents 300 km/h. 2. Higher tire speed ratings are more expensive. Tires with different speed ratings also vary in price. For tires of the same size and specifications, a W-rated tire is definitely more expensive than a V-rated tire because the W-rated tire has a higher load capacity. Additionally, higher-rated W tires not only have the advantage of higher maximum speed but also offer superior durability and resistance.
As an average car owner, I often pay attention to the letters on tires, which actually represent the tire performance rating system. Simply put, the letters are used to evaluate a tire's traction, heat resistance, and durability. The most common is the UTQG rating, for example, traction grades from A to C: Grade A performs best on slippery roads, providing more stable braking in rainy conditions; temperature grades A, B, C: Grade A can withstand high temperatures, making it less prone to overheating during long highway drives; treadwear is indicated by a number, such as 200, with higher numbers meaning the tire lasts longer. When buying new tires, I always compare these ratings, prioritizing Grade A traction and temperature for better safety. Especially in winter or during highway trips, good ratings can reduce the risk of skidding, offering great value for money.
