What are the pros and cons of 21-inch wheels for the Cayenne?

[OAaliyah]

Here are the detailed pros and cons of 21-inch wheels for the Cayenne: 1. Advantages: (1) Stronger load-bearing capacity: Small wheels usually use steel materials to save costs, but large wheels are made of aluminum alloy, especially those produced by forging processes. The load-bearing capacity of such wheels is five times that of ordinary steel wheels. (2) Improved cornering performance: After wheel modification, the contact area increases, enhancing the vehicle's stability during cornering and significantly improving its cornering performance. 2. Disadvantages: (1) Reduced vehicle performance: Large-size wheels affect acceleration and braking performance. As the wheel size increases, the width also increases accordingly. Larger and wider wheels naturally have greater weight, requiring more power consumption to drive them, which impacts acceleration performance. (2) Increased fuel consumption: Large wheels have an advantage in diameter, and the corresponding tread width is also larger. The benefit is that the increased contact area between the wheels and the road surface enhances grip, but the trade-off is increased friction, leading to a certain degree of higher fuel consumption.
