What model of tires does the Aion S use?
3 Answers
The tire model for the Aion S is 215/55R17. The first number, 215, represents the tire width of 215MM. The 55 indicates that the tire's aspect ratio is 55%, meaning the section height is 55% of the width. The 17 represents the rim diameter of 17 inches. The letter "R" in the middle stands for radial tire. The Aion S tires are from the Michelin brand, and the spare tire is full-size. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the vehicle frame near the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle, and check to ensure the jack is at a right angle to the ground; Remove the hubcap and loosen the nuts counterclockwise. Do not completely remove the nuts; just loosen them enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn, not the tire; Turn the nuts counterclockwise until they are loose. Repeat this step for all lug nuts, then completely remove the nuts; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model number, the tire also displays 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 specified conditions. Letters from A to Z represent certified speed ratings ranging from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim size compatible with the tire for practical use, such as standard rim 5.00F.
I have been driving the Aion S for two years and found that the original tires usually come in the size 215/55 R17, with brands possibly including Michelin or Goodyear, depending on the version. My car is the Plus version, and the tires perform steadily during daily city driving, offering good noise reduction at low speeds without affecting in-cabin comfort. Tire performance impacts the range of electric vehicles—low pressure tends to increase energy consumption, so I check the tire pressure monthly and keep it at the recommended value. When replacing tires, I opt for energy-efficient ones that balance durability and low rolling resistance, costing about 800 yuan per tire. Overall, the original configuration is quite reasonable, but wear is faster on poor road conditions, so I recommend getting a wheel alignment every 10,000 kilometers to extend tire life.
When driving the Aion S, the factory-fitted tires are mostly in the 215/55 R17 specification, while higher-end models like the Max version may be upgraded to 235/45 R18, commonly from brands like Michelin or Continental. Tires are crucial for driving safety, as good grip can shorten braking distance during emergency stops, giving me extra confidence on highways. For maintenance, regular tire rotation ensures even wear, and tread depth should be checked every 5,000 kilometers—replace them if it's less than 3 mm. Aging tires also affect handling stability, increasing the risk of rear-wheel skidding after rain. Choosing energy-efficient tires can improve efficiency by about 5%. Overall, safety comes first—factory settings are reliable, but don’t neglect maintenance.
