Is the tire specification indicated on the vehicle license?

The items marked on the vehicle license include the license plate number, vehicle type, owner, address, usage nature, brand model, vehicle identification code, engine number, registration date, and issuance date. The tire size is not indicated. Methods to check tire specifications: The international standard tire code represents the section height and aspect ratio in millimeters as a percentage, followed by the tire type code, rim diameter (in inches), load index (allowable load-bearing mass code), and allowable speed code. For example, 175/70R1477H: 175 indicates the tire width is 175 mm, 70 means the aspect ratio of the tire section is 70% (i.e., the section height is 70% of the width), the rim diameter is 14 inches, the load index is 77, and the allowable speed is H-grade. Precautions for replacing car tires: When selecting tires, the specifications should match the previous tires and must be the same as the other tire on the same axle, including speed rating, load index, tread pattern, brand, size, etc., to ensure safe driving. The valve stem should also be replaced because, after changing the tire, the aging cycles of the new tire and the valve stem differ. During the new tire's lifespan, the valve stem may develop issues, which are not easily noticeable. Therefore, it is advisable to replace the valve stem when changing tires. Installation direction and inflation: If using the original factory tire, follow the manufacturer's installation requirements. For non-original tires, the side with the production date usually faces outward. For directional tires, align the arrow on the wheel with the direction of the car's forward movement. During inflation, fill the tire to the maximum allowable pressure and then reduce it to the manufacturer's specified standard pressure.
