Car tire model numbers are located on the sidewall of the tire. In the tire specifications, the number before the slash represents the tire's section width, the number after the slash represents the aspect ratio, 'R' stands for radial tire, and the number following 'R' indicates the rim diameter. Tire model markings mostly appear as: 215/70R15. The meanings of these numbers are: 215 represents the tire section width in millimeters (mm), with general tire widths ranging from 145 to 285mm in 10mm increments. 70 is the aspect ratio, which is the ratio of the tire sidewall height to the tire section width, with 70 representing 70%. Typical tire aspect ratios range from 30% to 80%. 'R' is the abbreviation for Radial, indicating the tire has a radial structure, and 15 is the rim diameter in inches. The functions of tires are: to transmit driving force, braking force, and steering force for vehicle operation; to support vehicle loads; and to reduce and absorb vibrations and impact forces during driving. Tire maintenance methods include: regularly cleaning stones from tire treads; minimizing exposure to direct sunlight; promptly checking tire pressure; paying attention to suspension maintenance; regularly inspecting front wheel alignment; and adopting careful driving practices by choosing road surfaces carefully, avoiding objects that could puncture or damage tires, and steering clear of chemical spills that could corrode tires.

I always drive to and from work, and the tire model is located on the sidewall of the tire, making it particularly easy to find. Just crouch down and walk around the tire, and you'll see a combination of numbers and letters, such as 215/65R16. This indicates the tire's width, aspect ratio, and rim size. Knowing this location is crucial, especially when replacing tires, as the correct model must be matched; otherwise, it can affect driving stability and even lead to safety issues. Every time I wash my car, I take a photo of the tire sidewall with my phone and save it. This way, when it's time to replace the tire, I can quickly reference the model to purchase a new one, saving time and ensuring peace of mind, while also avoiding the waste of money from buying the wrong tire.

As a long-time car enthusiast, the tire model is always located on the sidewall of the tire. Just bend down and you'll spot those markings, usually in a format like P225/55R17. These numbers represent the tire's specific specifications: the first is the width (in millimeters), the second is the aspect ratio, followed by the construction type such as R for radial tires, and finally the rim diameter (in inches). Understanding these is crucial for maintaining vehicle performance, as different models affect grip, fuel efficiency, and noise levels. I often compare the original factory model when selecting tires to ensure they meet the vehicle's requirements. I also recommend checking the tire condition before long trips to prevent accidents caused by aging.

Focusing on driving safety, I emphasize that the tire model is prominently displayed on the sidewall of the tire, easily visible at a glance, such as markings like 195/65R15. Regular inspection is crucial to ensure that new and old tires have matching models, preventing uneven wear or the risk of a blowout. I recall an instance on the highway where unstable tire pressure was caused by mismatched models. Now, I've developed a habit of checking the sidewall markings every time I refuel, taking photos or jotting them down in a notebook for reference. This simple action ensures smooth and safe travels.
