What does the tire model 175 mean for the Weizhi v5?
2 Answers
The Weizhi v5 has two tire size models: 175/65R14 and 185/65R14. The first number, 175, indicates that the tire width is 175 mm. The number 65 represents the tire's aspect ratio of 65%, meaning the section height is 65% of the width. The letter R stands for radial tire, and 14 denotes the rim diameter of 14 inches. The Weizhi v5 has a top speed of 180 km/h and a fuel consumption of 6.1L per 100 km. In addition to the model, tires also display the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as a standard rim of 5.00F.
Last time I went to the shop to change tires, the owner told me that the Weizhi V5 comes with factory-fitted 175-size tires. This 175 refers to the tire tread width of 175 millimeters, just like the size of a foot—the larger the number, the wider the tire. Having driven this car for over five years, I’ve found that 175-width tires perform quite steadily on city roads, with less tendency to drift when taking curves and relatively low tire noise. However, wider tires do increase fuel consumption slightly. The Weizhi V5 strikes a good balance between economy and safety with this size. When replacing tires, I recommend checking the full specifications, such as 175/65 R14, where 65 is the aspect ratio and R14 indicates the rim size. The factory-fitted 175 size is scientifically justified, so avoid arbitrarily switching to wider sizes, as it could affect steering and fuel efficiency.
