What Is the Difference Between 215 45R17 and 215 50R17 Tires?
The main difference between these two tire sizes is the aspect ratio. The 45r17 tire has an aspect ratio of 45, meaning that the sidewall height is 45% of the tire’s width.
The 50r17 tire has an aspect ratio of 50, meaning that the sidewall height is 50% of the tire’s width. This means that the 50r17 tire will have a taller sidewall than the 45r17 tire.
How Does the Aspect Ratio Affect the Performance of the Tire?
The aspect ratio can affect the tire’s performance in terms of handling, comfort, and fuel efficiency. A lower aspect ratio (such as 45) generally results in better handling and performance, but a harsher ride.
A higher aspect ratio (such as 50) generally results in a more comfortable ride but may impact performance and fuel efficiency.
Are 215 45R17 Tires Better than 215 50R17 Tires?
It depends on what you are looking for in a tire. If you prioritize handling and performance, then the 45R17 tire may be a better choice for you. If you prioritize comfort and a softer ride, then the 50R17 tire may be a better choice.
