* Wheel Well Clearance: 22-inch rims, especially with low-profile tires, will likely have insufficient clearance within the wheel wells of the Impala SS. This could lead to rubbing against the fenders, suspension components, or brake calipers, especially during turns or when the suspension is compressed (e.g., hitting a bump).
* Tire Sidewall Height: Larger rims necessitate lower-profile tires to maintain the overall diameter close to the original size. Low-profile tires offer less sidewall protection, increasing the risk of damage to the rims and tires from potholes and other road hazards. The ride will also be significantly harsher.
* Brake Caliper Interference: The larger rim diameter might interfere with the brake calipers. This is a serious safety concern and could require modifications to the brake system.
* Speedometer Calibration: Changing the overall tire diameter significantly affects the speedometer's accuracy. You'd likely need a speedometer recalibration to ensure accurate readings.
While some aftermarket parts might *seem* compatible, proper fitment requires more than just bolt pattern matching. You need to consider offset, backspacing, and overall diameter. Before attempting such a significant wheel upgrade, it's strongly recommended to consult with a tire and wheel specialist or a reputable automotive shop to determine the feasibility and potential safety implications. They can verify if 22-inch rims are compatible with your specific Impala SS model and make any necessary adjustments or modifications. Otherwise, you risk significant damage to your vehicle and potential safety hazards.
