1 Answers
The differences between 91V and 91W tires lie in their speed ratings and load indexes, with specific details as follows: Speed rating: The 'V' indicates that the tire can sustain a maximum speed of 240 km/h, while the 'W' denotes a maximum speed capability of 270 km/h. Load index: Both 91W and 91V tires can bear a load of 615 kg. Below is extended information about automotive tire specifications: Specification representation: Tires are crucial components of vehicles, coming in various specifications and models suitable for different vehicle types. Specification markings are typically found on the tire sidewall as a series of alphanumeric characters, representing tread width, aspect ratio, type, rim diameter, load index, and speed rating. Speed rating: Tire speed ratings are categorized from A to Z based on their maximum sustainable speeds, with the A class further divided into eight subcategories (A1-A8). The later the letter appears in the alphabet, the better the tire's performance.
