To choose the right tyre, it's important to know the tyre size. Here's an example of a tire size: 235 45R18 98W.
235: Refers to the width of the cross-section of the tire, in millimeters. 45: Indicates the height-to-width ratio of the tire, that is, the ratio of the height of the tire to the width. A lower number means a flatter tire, and a higher number means a taller tire. R: stands for radial tires. 18: refers to the inner diameter of the tire, measured in inches, that is, the size of the wheel mesh. 98: Indicates the load index of a single tire of this tire, which can carry a maximum weight of 750 kg. W: Indicates the speed class of this tire, with a top speed of 270 km/h. When parsing tire sizes, care should be taken to understand the meaning of each number as well as its units. Make sure that the size of the tires you buy matches the size of the tires installed in the original car to meet the needs of the vehicle. What are the other important information on the tires?In addition to the size information, there are other important pieces of information to pay attention to:
Brand and origin: It is important to know the brand and origin of the tire. For example, this tire may be Dunlop branded, and although it belongs to a Japanese brand, it is actually made in China. The distinction between domestic and imported tires may vary.
Load Index and Speed Class: The number on the tire represents the load index and speed class of the tire.
For example, this tyre has a load index of 98 and carries a maximum weight of 750 kg, while the speed class is W and has a top speed of 270 km/h. Please note that each vehicle has specific load index and speed class requirements, so it should be matched to the tires installed in the original vehicle.
Date of manufacture: There is usually a circle behind the DOT logo on tires with some numbers inside. For example, 20 represents the year the tire was produced, and 32 represents the 32nd week of the year. By looking at the production date, it is possible to determine whether the tire is newly produced or in stock. At the same time, it is necessary to pay attention to whether there are any signs of modification to avoid buying stock tires that have been renumbered. The above is the important information you need to pay attention to when buying tires. By knowing this information, you will be better equipped to choose the right tires for your vehicle and avoid being misled or deceived by unscrupulous merchants.
