1. Bolt pattern: The bolt pattern of the new wheels (5x4.5) must match the original factory bolt pattern (5x115). They are not compatible.
2. Offset: The offset measurement specifies how far the wheel sits in or out from the hub face. A significant difference in offset from the original specifications can affect various components, including suspension and steering geometry, and may not be safe or recommended. In your case, your rim has an offset of -16 while the factory rim has an offset of 25. This difference in offset means the new rims would be displaced towards the front of the vehicle by almost 2 inches, which is significant.
3. Diameter and Width: Your rims are 15 inches in diameter, while the factory rims are 17 inches. This can significantly alter your vehicle's ride quality and potentially impact the proper fitment of tires and clearance with other components such as brake calipers.
4. Tire Compatibility: The diameter and width difference between your new rims and the factory rims will also impact appropriate tire size selection and may require different tires than what you currently have on your vehicle.
Since the critical details like the bolt pattern, offset, and diameter of the proposed rims don't match the factory specifications of your 2007 Dodge Charger SXT, it is not recommended to install the 15x8 Klassic Keystone rims without proper fitment and safety checks. Consult with reputable tire and wheel experts or specialists to determine the right specifications for your vehicle and suitable options.
