Considerations for Smaller Tires

- Better Stability: Wider tires can enhance stability during high-speed driving or cornering, making your ride feel more planted.
Considerations for Bigger Tires

- Fuel Economy: Bigger tires can increase rolling resistance, which may negatively impact fuel efficiency.
- Speedometer and Odometer Issues: Just like with smaller tires, larger tires can affect the accuracy of your speedometer and odometer.
