What is the tire model specification of JAC Heyue?
4 Answers
JAC Heyue's tire model is 205/55R16. The first number 205 represents the tire width of 205MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 16 represents the rim diameter of 16 inches. The middle letters or symbols have special meanings: "X" denotes high-pressure tires; "R" and "Z" denote radial tires; "-" denotes low-pressure tires. The maximum speed of JAC Heyue is 175km/h, and the fuel consumption per 100 kilometers is 7.5L. In addition to the model, the tire also carries the following common data: Tire cord material: represented by Chinese Pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, ZG for steel radial cord tires. Speed rating: indicates the maximum speed at which the tire can carry a 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 compatible with the tire for practical use, such as standard rim 5.00F.
I remember most Jianghuai Heyue models use tire size 195/55 R15, but it depends on the specific year and configuration. The 195 refers to the tire width of 195 millimeters, 55 represents the aspect ratio, and R15 means 15-inch rim diameter. This size is quite suitable for city driving, offering decent grip without consuming too much fuel. If your car has 185 or 205 tires, the previous owner might have modified them. When replacing tires, it's best to stick to the original size; otherwise, the steering feel and speedometer readings may deviate. The most accurate way is to check the embossed markings on the tire sidewall or refer to the factory label near the passenger side door.
The original tires for the JAC Heyue are typically sized 195/55 R15, which I specifically noticed while driving this car. The first number, 195, refers to the tread width in millimeters; 55 indicates that the tire's thickness is 55% of the width; and R15 denotes a 15-inch wheel diameter. This size is actually quite common, offering various brand options when replacing tires. However, it's worth noting that some 2015 manual transmission models use 205/50 R16 tires. A wider tire may slightly increase fuel consumption but provides better stability at high speeds.
Most JAC Heyue owners report that the factory-installed tires are 195/55 R15. You can confirm this by checking the sticker on the door frame or the sidewall markings. When replacing tires, stick to the original size: for example, a width narrower than 195mm may cause skidding, while wider tires increase fuel consumption. Changing the aspect ratio from 55 to a much higher value makes the car feel like a boat, while a lower ratio may damage the suspension due to excessive bumpiness. It's recommended to inspect tire condition every 50,000 kilometers; if the tread wear indicators (triangular marks on the sidewall) show exposed horizontal grooves, it's time for replacement.
