What does 105V on a tire mean?
2 Answers
In the tire marking 105V, the number 105 indicates the load index of the tire, meaning each tire can carry a maximum load of 925KG. The letter V indicates that the tire has a maximum speed rating of 240 kilometers per hour. The load index of a tire refers to the maximum load capacity the tire can bear when inflated to the specified pressure. The speed rating of a tire indicates the maximum speed at which the tire is allowed to travel, usually represented by uppercase English letters and marked on the sidewall of the tire. Different letters represent different speed ratings. For example, L indicates a maximum allowed speed of 120 kilometers per hour, and T indicates a maximum allowed speed of 190 kilometers per hour.
The 105V marking on the tire is an important identifier. The number 105 represents its maximum load capacity, equivalent to approximately 925 kilograms, while the letter V denotes the speed rating, indicating that the tire can safely handle speeds up to 240 kilometers per hour. I remember one time when I was driving with too much luggage and didn't pay attention to the tire's load limit. As a result, I felt the car shaking violently on the highway. Upon checking later, I realized it was due to overloading and nearly caused an accident. Since then, I've developed a habit of verifying these numbers every time I buy new tires or before hitting the highway to ensure I don't exceed the limits. Typically, SUVs or larger vehicles often use similar specifications to prevent issues when carrying heavy loads. This is fundamental to safe driving—never overlook these small details to avoid serious consequences.
