Performance Implications
Choosing the right tire size is not just about fitting the wheel. It has direct implications for performance:
- Handling: A wider tire, like the 245/40R18, provides more contact with the road, enhancing grip during cornering.
- Ride Quality: The aspect ratio affects how much sidewall flex you have. A lower aspect ratio can lead to a stiffer ride but better handling.
