* Specific Rim Offset: The offset of the wheel (how far the mounting surface is from the center line) is crucial. The wrong offset can cause rubbing against the suspension, brakes, or body. You'll need to find rims with an offset specifically designed to fit a 2007 Charger, likely requiring research or consultation with a wheel and tire specialist.
* Tire Size: Even with the correct offset, the tire diameter (including sidewall height) will influence clearance. A 22-inch rim will necessitate a tire with a low profile to avoid rubbing. Too large a tire could interfere with the fenders or suspension.
* Suspension Modifications: Depending on the rim and tire combination, you might need to adjust or upgrade your suspension components (like lowering springs or coilovers) to prevent rubbing.
* Brake Caliper Clearance: Larger rims can sometimes interfere with the brake calipers. You need to ensure sufficient clearance.
In short: You'll likely need to do significant research to find 22-inch rims that will fit your 2007 Dodge Charger without requiring modifications. It's strongly recommended to consult with a wheel and tire specialist or use a wheel fitment guide specifically for your year and model of Charger before purchasing. Improperly fitting wheels can be dangerous and affect your vehicle's handling.
