* Wheels with the correct bolt pattern: The Impala has a specific bolt pattern (number of lug nuts and their spacing). You MUST find 22-inch wheels with the *exact same* bolt pattern. Incorrect bolt patterns are dangerous and will not fit. Check your owner's manual or a reliable online resource (like Tire Rack) to find your Impala's bolt pattern.
* Correct wheel offset: The offset determines how far the wheel sits in or out from the hub. An incorrect offset can cause rubbing against the suspension, brakes, or body of the car. You'll need to research the ideal offset range for your Impala with 22-inch wheels. This often requires consulting with a wheel and tire specialist or using a wheel fitment calculator.
* Appropriate tire size: Even with the right wheels, the wrong tire size can also cause rubbing. The overall diameter of the wheel and tire combination should be reasonably close to the stock size to avoid speedometer inaccuracies and potential issues with the ABS system and transmission. A tire shop or online calculator can help determine compatible tire sizes for your new rims.
* Possible suspension modifications: With 22-inch rims, there's a good chance you'll need to adjust or modify your suspension. Larger rims and tires mean a larger overall wheel and tire diameter, which can cause rubbing on the fenders, especially during turning. This might involve things like lowering springs, coilovers, or even fender rolling/flares.
* Professional installation: It's highly recommended you have a professional shop install the wheels and tires. They have the expertise to ensure proper fitment and balance the wheels to avoid vibrations.
In short: Just buying 22-inch rims isn't enough. You need to carefully research the correct specifications (bolt pattern, offset) and consider potential suspension modifications and tire size to avoid problems. The expense will go beyond the cost of the rims themselves. It's a significant undertaking that is best left to experienced professionals unless you have significant automotive mechanical knowledge.
