Are wider rims better for Mercedes?
For example, larger diameter wheels are good at increasing tire grip, which means better handling and a more responsive vehicle. Additionally, a wider rim makes for more stable tires, especially on corners. It has often been said that to have good cycling wheel performance, there is a rule that the external rim width of a wheel should be at least 105% of the width of the tyre, or that there is a simple relationship/formula that will predict the aerodynamic performance of a wheel based on rim width vs tyre width.
Why do Mercedes rims crack?
It could be that the load the car has been carrying is simply too great, or that the rims are old and have been mistreated for many years. Steel rims are renowned for their durability and strength, making them less susceptible to damage from potholes or debris.
