What does 100v on a tire mean?

Tire 100v represents: 100 refers to the load index, indicating a maximum load capacity of 800kg at standard speed; v is the speed symbol, representing a maximum speed of 240km/h under standard load. The load index expresses the maximum load a single tire can bear in coded form. For example, a tire with a load index of 100 has a maximum load capacity of 800kg. Taking a common passenger car tire specification as an example: 195/60R14 86H, where 195 indicates the section width, 60 represents the aspect ratio, R denotes the tire construction code, 14 stands for the rim diameter, 86 is the load index, and H indicates the speed rating.
Recently while changing tires for my car, I researched this marking - 100V refers to the tire's specification code. The 100 represents the load index, meaning each tire can carry a maximum weight of 800kg, and V is the speed rating, indicating the tire can safely reach a maximum speed of 240km/h. This is crucial for daily driving, especially on highways. If your driving speed frequently exceeds 200km/h or the vehicle carries heavy loads (such as when transporting goods), choosing the wrong tire specifications may lead to dangerous blowouts. I recommend car owners check their vehicle manual before purchasing new tires to ensure load and speed ratings match - for example, SUVs typically require higher load indexes. Regularly inspect tire wear to prevent accidents. This marking is usually printed on the tire sidewall alongside size information like 195/65 R15.
As a frequent long-distance driver, I find the 100V rating very important. The 100 indicates each tire's maximum load capacity is 800kg, while the V means the tire is designed for speeds up to 240km/h. Choosing the right tires directly impacts driving safety and lifespan - if the vehicle load exceeds 800kg or frequently speeds, tires are prone to aging and cracking. I've also noticed weather and road conditions have effects; for example, V-rated tires provide better grip when driving at high speeds on wet roads. When replacing tires, don't just look at price - match the original specifications. Accidentally buying tires with lower load indexes could cause problems when fully loaded.
