What do 97v and 97w tires mean?
2 Answers
97v and 97w tires mean: 97 represents the load index of the tire, indicating that the tire can bear a weight of 730kg. w and v represent the speed rating of the tire, with w being 270km/h and v being 240km/h. Here is some related information about the tire load index: 1. Introduction: The load index refers to the numerical value representing the maximum load that a tire can bear under specified conditions at maximum air pressure. 2. Classification: Generally speaking, the further back the letter representing the tire speed rating is in the alphabet, the better the performance of the tire, and the higher the price. Tires with different speed ratings are suitable for different applications. P—T grade tires (maximum speed 150—190km/h) are suitable for small and compact cars, U—V grade tires (maximum speed 200—240km/h) are suitable for mid-to-high-end cars, and the best-performing W—Z tires, which can bear a maximum speed between 240—300km, are usually used in large luxury cars and super sports cars.
The markings 97V and 97W on tires indicate load capacity and maximum speed limits. Specifically, 97 represents a load index of 730 kilograms, meaning one tire can bear 730 kilograms. V denotes a speed rating of up to 240 kilometers per hour, while W is 270 kilometers per hour. I've driven many types of vehicles, such as SUVs or sports cars, and these markings are usually on the tire sidewall. When purchasing tires, make sure they match the vehicle manual—don’t replace them with the wrong grade. Overloading may cause a blowout, and excessive speed can affect handling safety. For regular household use, I think V is sufficient unless you frequently drive on highways or seek a racing feel. Different vehicle types have different needs, so when inspecting tires, also check wear to ensure longevity.
