Goodyear tires are divided into three grades: low, medium and high, which are distinguished by different patterns and specifications. Goodyear automobile tires have 10 different patterns on official website. Generally speaking, there are four categories of Eagle series products, Sanneng, Ride-resistant and Guarantee series products, and seven different models of automobile tires. Eagle series products are the most accurate products for Goodyear tire positioning.

"P" or no letter sign: it means a new energy bus tire.

ECE certification mark and serial number: Indicates that the tire conforms to the specifications of the relevant pneumatic tires of the European Union National Ethnic Committee (ECE).

DOT: It means that this tire meets the testing standards required by the British Ministry of Transport.

TWI: tread wear mark point, indicating the position of tire tread wear mark. You should check this sign on time to make sure the tread pattern is deep enough. In most cases, the minimum pattern depth is 1.6 mm.

Speed class (A-Z): Speed class refers to the maximum speed allowed under reasonable pumping pressure and load. The key point is that the letters A to Z indicate the verified speed grade of 4.8 km/h to 300 km/h, but now most new energy bus tires are between S and Y, in other words, the maximum tolerable speed is between 180-300 km/h, for example, the speed grade V indicates that the tires have a larger running speed of 240 km/h. When you buy tires, try to make them as fast as possible.
