Why Tire Size Matters
Choosing the correct tire size is crucial for several reasons:
- Performance: The right tire size ensures optimal handling and stability, especially during cornering and braking.
- Fuel Efficiency: Incorrect tire sizes can lead to increased rolling resistance, which may negatively impact fuel economy.
- Safety: Using the wrong tire size can compromise traction and braking performance, which is critical for safe driving.
- Comfort: The correct tire size contributes to a smoother ride, absorbing bumps and imperfections in the road.
