Zhijun's original tire configuration model is 195/60R14. The first number 195 indicates that the tire width is 195MM, 60 means the aspect ratio of the tire section is 60%, that is, the section height is 60% of the width, the letter R stands for radial tire, and 14 represents the rim diameter is 14 inches. Zhijun has a top speed of 187km/h, accelerates from 0 to 100km/h in 12.5 seconds, and has a fuel consumption of 7.9L per 100km. In addition to the model, the tire is also marked with the following common data: Tire cord material: represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Commonly used speed ratings are: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: indicates the rim specification that matches the tire. For practical use, such as standard rim 5.00F.

I've been driving a Volkswagen Santana for almost ten years and am very familiar with its tires. The factory standard size is 195/65 R15, which means the tire width is 195 millimeters, the height is 65% of the width, and the wheel diameter is 15 inches. This size provides good stability—no drifting on highways and easy handling in turns. For daily driving, I make it a habit to check the tire pressure every month, adjusting it to around 2.2 bar as indicated on the door frame. Too high or too low pressure increases fuel consumption and risks. When the tread depth falls below 1.6 mm, it's time to replace the tires. Last time I replaced them, I chose a durable brand in the same specification, which was both cost-effective and hassle-free. If upgrading to larger wheels, like 16 inches, the size must be adjusted accordingly to avoid speedometer inaccuracies and safety issues. For rainy conditions, tires with better drainage patterns are recommended for added confidence on wet roads.

When replacing the tires on my Volkswagen Santana, the original size was 185/60 R15. Last time when the old ones wore out, I opted for new ones of the same specification from the Chaoyang brand. They feel softer to drive on, with less bumpiness and quieter noise. The installation guy mentioned that you shouldn’t randomly change the specifications, as incorrect sizes can cause ABS failure—a friend of mine had an accident because of this before. Tire pressure should be checked regularly; I have an app on my phone that alerts me, and generally, 2.3 bar is the most suitable. Tire lifespan is about 50,000 kilometers, and regular rotation can extend their use—I get them rotated at the shop every six months. Before long trips, check the tires for cracks or bulges and address any issues promptly to prevent accidents. When encountering potholes on the road, slow down to avoid blowouts or rim damage. With proper maintenance, tire performance stays optimal.

Having driven the Zhi Jun for many years, the tire specification 195/65 R15 is the standard configuration. This size is crucial for driving safety, with the 195mm width providing sufficient contact area, and the 65 aspect ratio balancing comfort and handling. Regular inspections are essential, including checking tire pressure and wear. Improper pressure can cause uneven wear, increased fuel consumption, or the risk of a blowout. I often use a simple gauge to measure tire pressure, keeping it at the recommended level on the door sticker. If the tread depth falls below the minimum safety line, replace the tires immediately. Choosing a brand that matches the specifications enhances grip, reducing the chance of slipping in rain or snow. During replacement, ensure proper installation and balancing to avoid vibrations that could damage the suspension. Small details ensure greater safety.
