What is the ET value of the original 17-inch wheel hub for the MG6?

The ET value of the original 17-inch wheel hub for the MG6 is 50. Meaning of wheel hub ET value: It represents the offset value of the wheel hub, indicating the deviation distance from the wheel centerline to the mounting surface of the hub. ET originates from the German term 'Einpress-Tiefe,' which literally translates to 'insertion depth.' ET value scale: If the ET value is a larger negative number, the wheel will protrude more outward when mounted on the vehicle. ET refers to the distance between the mounting surface of the hub and the centerline in the width direction of the hub. Generally, the smaller the value, the more the wheel protrudes outward from the wheel arch. Some wheels even have negative ET values, typically seen in modified off-road vehicles.
I've been driving my MG6 for over two years, and the original 17-inch wheels have an ET value of approximately 45mm. This offset is like the mounting offset of the wheel, determining how close or far the wheel is from the car body. A too small ET will make the tires stick out, looking cool but prone to rubbing against the fenders; a too large ET will make them tuck in, affecting cornering stability. I recommend checking the vehicle manual or confirming directly at the 4S dealership, as there might be slight adjustments for different year models. Don't randomly change the ET when modifying; I've seen friends experience strange noises after modifications, even accelerating tire wear. Remember, the factory settings are optimized for safety and performance. Regularly checking the wheel condition can prevent sudden issues, especially before high-speed driving.
