What does 100h on a tire mean?

Here is an introduction to the meaning of 100h on a tire: 1. The 100h marking on a tire represents two parameters: load capacity and speed, with the numerical part being the load index of the tire. 2. The meaning of 100 is that the load capacity at the rated speed is 800KG, and the letter part is the speed rating of the tire, with h indicating that the tire can support a maximum speed of 240KM/H under the rated load. 3. When selecting the load index of a tire, it needs to be calculated based on 1.5 times the total vehicle weight. For example: 100 represents a load index of 800kg. Generally, a passenger car has 4 tires, multiplied by 4 equals 3200kg. Calculating at 1.5 times, four tires with a load index of 100 can support a vehicle weighing below 2133kg. The speed rating should be selected based on actual conditions and the vehicle's performance parameters, and this index is unrelated to the number of tires.
The tire code 100h actually refers to the tire's specification. The number 100 is the load index, typically indicating that the tire can bear a maximum weight of around 800 kilograms. The letter h is the speed rating, meaning the tire can safely handle speeds up to 210 kilometers per hour, which is reassuring when driving on highways. I find this crucial because choosing the wrong specifications could lead to tire blowouts or unstable handling, especially when traveling with a full load of passengers, where the load index becomes particularly important. Additionally, different speed ratings exist, such as v for 240 km/h and t for 190 km/h, with h being more common for mid-sized vehicles. I usually refer to the vehicle owner's manual for recommended tire parameters to ensure compatibility with the car's design. Weather and road conditions also affect tire performance; for example, high speeds on wet roads can be unsafe, so regular checks on tire wear and pressure help mitigate risks. In summary, 100h is a practical specification suitable for most daily driving scenarios, and it's essential to verify these details when replacing tires.
In the tire code 100H, the number 100 represents the load index, indicating that a single tire can bear approximately 800 kilograms of weight, suitable for the vehicle's total weight. The letter H denotes the speed rating, meaning a maximum safe speed of 210 kilometers per hour, which is crucial when selecting tires. I believe safety is the top priority. Overloading or exceeding the speed limit can easily lead to loss of control or tire blowouts, especially when driving in rainy conditions or on mountainous roads. Every time I change tires, I first check the vehicle manual to ensure the indices match. For example, my SUV uses a similar specification to handle the load for family trips. Additionally, understanding different speed ratings, such as H compared to Q (160 km/h) and S (180 km/h), helps in making a reasonable choice. Developing a habit of regularly checking tire tread and pressure can prevent accidents. After all, tires are the only part of the vehicle in contact with the ground, and they should be replaced promptly when they wear out.
In the tire marking '100h', the number 100 refers to the load capacity, which can roughly carry 800 kilograms, while the 'h' indicates that the maximum safe speed it can reach is 210 kilometers per hour. Having driven many cars, I find this specification quite common, suitable for city driving or occasional highway use. It's crucial to check this code when selecting tires, as buying one with too low a load or speed rating can be dangerous if overloaded or speeding, increasing the risk of accidents. For regular maintenance, I recommend checking tire wear and pressure every six months.
