The wheel size of the Oshan X7 is 20 inches. The wheel hub is the rotating part of the wheel steel inside the tire, connected by columns to the wheel core, and is the metal component that supports the tire and is mounted on the axle. Precautions for wheel hub installation include: 1. Regularly inspect the wheel hub for early signs of wear; 2. The wheel hub is sensitive and requires the correct methods and appropriate tools; 3. Do not disassemble the wheel hub or adjust the sealing ring of the wheel hub unit. Maintenance methods for the wheel hub include: 1. When the vehicle is in a humid area, clean the wheel hub frequently to prevent salt corrosion on the aluminum surface; 2. If necessary, after thorough cleaning, apply wax to maintain the wheel hub's shine; 3. When the wheel hub is hot, allow it to cool naturally before cleaning. Do not use cold water for cleaning, as it may damage the aluminum wheel hub, cause brake disc deformation, and affect braking performance. Using detergent to clean the wheel hub may cause chemical reactions on the surface, leading to loss of shine.

The wheel size of the Oshan X7 mainly depends on the specific configuration. The base model comes with 17-inch wheels, while the mid and high-end models are upgraded to 19-inch wheels. I specifically checked the official configuration sheet to confirm this information. The 19-inch wheels provide excellent stability, especially with noticeably better grip at high speeds, although they produce relatively more tire noise. While the 17-inch wheels may not look as imposing, they offer a more comfortable ride over speed bumps, and tire replacements are much cheaper. I recommend checking the sidewall markings on the actual car's tires before purchasing, as they display the specifications. Personally, I think the mid-range 19-inch wheels offer the best value—the large wheels complement the car's 4.7-meter body very well.

Regarding the wheel size issue, it really depends on the trim level. The entry-level Oshan X7 comes with 17-inch wheels, while other trims mostly feature 19-inch ones. A friend of mine who drives this car actually measured the wheels on his luxury trim - the diameter does approach half a meter. Larger wheels significantly improve handling, especially in reducing body roll during cornering. However, be aware that the 19-inch wheels come with thinner tires, so you'll need to be extra cautious over potholes to avoid rim damage. For mainly urban driving, the 17-inch wheels are perfectly adequate and more worry-free on rough roads.

The Oshan X7 does indeed have different wheel sizes across its configurations. The standard version comes with 17-inch wheels, while mid-to-high trim levels feature 19-inch wheels. This difference not only affects appearance but also the actual driving experience. The larger wheels are paired with tires that have a lower aspect ratio, providing more precise steering at high speeds. However, each 19-inch tire costs about 200 yuan more, resulting in higher maintenance costs in the long run. Personally, I recommend focusing on actual needs: opt for 19-inch wheels if you frequently drive long distances, while 17-inch wheels are perfectly sufficient for city commuting. When picking up the car, remember to check the size parameters marked on the tires.
