**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.
