Will 2012 dodge charger rims fit on my 2000 jeep grand cherokee Laredo

Look online at a Dodge parts listing and see if they are the same bolt pattern, rim width and backspace (you don't want it rubbing on the brake caliper). If the Charger rims are wider but the same bolt pattern and larger diameter (to clear the brake caliper), then you need to find out if the extra rim width is on the inside (bolting face to rim inside) or outside face (bolting face to outside of the rim). "Inside space" requires wheel well clearance to the tire tread and "A-Arm" or axle clearance to the tire sidewall. If the tires stick out too far "outside space" then you should check for tire clearance to the "front fenders VS tire overall diameter" when turning while going thru a bump (where the tire is forced into the wheel well area further, then if going straight down the road) to make sure you don't need to either install a suspension lift or cut the wheel well opening larger and your state might require fender flares.
