Here's why:
* Tire width and backspacing: A 15x10 rim is very wide. The backspacing (the distance from the mounting surface of the wheel to the inside edge of the wheel) is critical. Incorrect backspacing can cause the tires to rub the fenders, frame, or suspension components, even without significant tire width. Wide tires significantly increase the load on the rear suspension.
* Traction bars: With wide tires, especially if you're using a powerful engine, the increased traction can cause axle wrap (the differential twisting under acceleration). Traction bars help to control axle wrap and improve traction. They are highly recommended for performance applications or even moderate power increases on a car like a Charger.
* Air shocks: Air shocks can help to control the increased load of the wide tires, but they are not essential. They offer adjustable ride height and stiffness, which can be beneficial for compensating for the increased tire width and preventing rubbing. However, standard shocks are often sufficient depending on tire choice, and how you drive.
In short: While you *can* technically fit 15x10 rims, the success depends heavily on the tire width and backspacing. Traction bars are strongly recommended to prevent axle wrap, especially with a powerful engine, and air shocks can help manage the increased load and ride height issues. Proper planning, including meticulous measurements and potentially professional consultation, is essential before committing to this setup.
