* Tire size: The overall diameter of the wheel and tire combination must remain relatively close to the original size to avoid speedometer inaccuracies, rubbing issues, and potential damage to the drivetrain. Larger rims often mean smaller profile tires to maintain overall diameter.
* Backspacing: This is the distance between the mounting surface of the wheel and the inner lip. Incorrect backspacing can cause the wheel to rub against the suspension, brakes, or body.
* Offset: Similar to backspacing, offset affects how far the wheel sits in or out of the wheel well. An incorrect offset can also lead to rubbing.
* Suspension: Modifications to the suspension (lowering or lifting) can affect the amount of clearance available for larger wheels and tires.
While some people may have successfully fitted larger rims, attempting to go significantly beyond the factory recommendations without careful consideration and potentially costly modifications is risky. You could experience rubbing, decreased handling, and potentially damage your vehicle.
To find a safe and appropriate size:
1. Check your owner's manual: It will list the recommended rim and tire sizes.
2. Consult a tire professional: A reputable tire shop can help you determine the largest rim size that will fit your 2000 Impala safely and without modifications. They can consider your specific vehicle, existing suspension, and desired tire size.
3. Online resources: Forums and websites dedicated to Chevy Impalas often have discussions on wheel and tire upgrades. However, always verify information with a professional.
In short, don't just look for the "biggest" – focus on finding the *best* fit that maintains safety and performance.
