Will 20 rims on a cls 500 Mercedes change the ride?

Yes, upgrading to 20-inch rims on a Mercedes CLS 500 can change the ride quality. Larger rims typically result in a stiffer ride due to reduced sidewall height of the tires, which can lead to less cushioning over bumps. Additionally, the handling may be improved due to increased responsiveness, but it can also result in a harsher driving experience, particularly on uneven surfaces. Ultimately, it depends on the tire choice and suspension setup as well.
