JAC Refine S3's tire model is 205/55R16, with both front and rear wheels using this size, specifically the Giti Comfort 221 series tires. The tire size specifications are marked on the sidewall of the tire, such as 205/55R16, where 205 represents the tire width in millimeters, 55 is the aspect ratio, R stands for radial tire, and 16 indicates it can be mounted on 16-inch rims. The JAC Refine S3 is equipped with a three-spoke multifunction steering wheel, wrapped in leather, integrating audio controls, cruise control, and Bluetooth functionality. The front of the vehicle features JAC's signature "Baopingkou" design, blending urban crossover SUV elements, presenting an overall stylish and dynamic appearance. The exterior details complement the whole design, including the intake grille with three prominent chrome strips.

When I drove the JAC Refine S3 before, I paid special attention to the tires. My model was purchased in 2016 and came with Giti tires, clearly marked as 205/55 R16. However, I heard that the base version might be equipped with 195/65 R15 tires, so it depends on your specific model and year. If you're unsure, the simplest way is to crouch down and check the markings on the side of the tire—there will definitely be a combination of numbers and letters printed there. When replacing tires, be careful not to randomly change the size, as it can affect the accuracy of the speedometer and also increase fuel consumption. Also, pay attention to tire wear regularly—front-wheel-drive cars are particularly prone to uneven wear, and you should consider replacing them after about 50,000 kilometers.

Having repaired cars for ten years, it's not uncommon for JAC Refine S3 owners to come to me for tire replacements. This model typically comes in two specifications: 205/55 R16 and 195/65 R15, depending on the trim level you purchased. The series of numbers on the tire sidewall acts as its ID—for example, 205 represents the tire width, 55 is the aspect ratio, and R16 indicates the rim diameter. The factory-fitted Giti and Kumho tires are both excellent choices, offering durability and affordability. If the tires on older models show signs of aging, such as fine cracks on the sidewalls, they should be replaced immediately, especially before summer highway driving, which can be particularly hazardous. Never opt for cheap retreaded tires when replacing them, as they provide poor grip and are prone to blowouts.

Last month, I helped a friend find a set of used tires for a JAC Refine S3 and did some research along the way. The tire specifications for this model vary by year. For example, the 2015 version commonly uses 205/55 R16, while the 2018 version switches to 215/55 R17. The most reliable way to check the tire model is to look at the raised letters on the sidewall—no need to guess. If you're considering modifications, it's advisable not to exceed 3% of the original size; otherwise, the tires might rub against the wheel arches when turning. Once, I encountered an owner who opted for cheap off-brand tires, and the braking performance was noticeably poor in the rain—quite scary. Don’t forget to check the spare tire as well, as its size often differs from the full-size tires.
