The phenomenon of wheels appearing to rotate backwards is caused by the persistence of vision in the human eye. When observing objects, images remain on the retina for a brief period, approximately between 0.05 to 0.08 seconds, creating the illusion of reverse wheel rotation. In reality, the wheels do not actually rotate backwards. Below is an introduction to wheel construction: 1. Rim: The part of the wheel that fits and supports the tire. 2. Spokes: The part of the wheel that connects to the axle hub and supports the rim. 3. Offset: The distance between the centerline of the rim and the mounting surface of the spokes. It can be positive offset, zero offset, or negative offset. 4. Flange: The part of the rim that maintains and supports the tire's direction. 5. Bead seat: Also known as the mounting surface, it contacts the tire bead and supports the radial direction of the tire. 6. Well: A depression of certain depth and width on the rim to facilitate tire installation and removal. 7. Valve hole: The hole for installing the tire valve.

I get really excited when I see high-end car wheels appear to spin backwards. In reality, the wheels aren't actually reversing - it's a visual illusion captured by the camera. When wheels rotate at high speeds with a slow camera shutter speed that can't keep up with the rotation rhythm, they appear to spin backwards in the footage. This phenomenon is common in high-performance sports car videos, especially with flashy wheel designs where patterns make the illusion more pronounced. I remember filming a sports car video where I had to use slow shutter speed to achieve this effect - switching to high shutter speed showed normal rotation. In reality, wheels must spin forward for the car to move. Don't be fooled by this harmless illusion - it's actually quite cool. Photographers sometimes intentionally create it to enhance video impact. Next time you see this, try changing your viewing angle or camera settings.

This phenomenon is called the stroboscopic effect, which is essentially an optical illusion. When the wheel rotates at high speed, the camera's frame rate isn't fast enough to capture the continuous movement of the wheel's edge, causing the brain to misinterpret it as rotating in reverse. High-end wheels often feature more intricate and complex designs, such as multi-spoke or lightweight structures, which create more visual disturbances during rotation and make the illusion more pronounced. Rest assured, this doesn't affect the vehicle's safe operation and only occurs in videos or slow-motion playback. If you want to avoid seeing it, you can adjust your camera to a higher shutter speed when recording, such as 1/1000 second or faster. In short, it has nothing to do with real driving—it's purely a meeting point of technology and visual perception.

I've only seen the wheels spinning backwards in videos; when actually driving, the wheels rotate steadily forward. This is an illusion caused by camera settings—when the wheels spin too fast, a slow shutter speed captures them in a way that resembles a movie effect. On high-end cars with smooth wheel designs at high speeds, this illusion is even more noticeable. Don't worry, it doesn't affect the car's performance or handling.
