Why are the front and rear tires of the Mercedes-Benz CLS300 different?

[RosalieLynn]

The reason for the difference in tire sizes between the front and rear of the Mercedes-Benz CLS300 is that this rear-wheel-drive vehicle has relatively high horsepower, requiring better traction from the rear tires. Therefore, high-horsepower rear-wheel-drive cars generally have wider rear tires to increase grip. Reasons why the front tires are not too wide: In rear-wheel-drive vehicles, the front tires perform the steering function, so they are not too wide. If they were too wide, the steering wheel would become very heavy, affecting handling. Reasons why the rear tires are wider: Choosing wider rear tires provides better road adhesion, allowing the vehicle's driving force to be fully utilized for improved performance. Additionally, rear-wheel-drive vehicles are slightly less stable in straight-line driving compared to front-wheel-drive vehicles, and wider rear tires can help compensate for this drawback to some extent.
