Changing out wheels on the Lincoln Town Car

There should be no problem with the same size rim at all. Zee

My biggest concern would be the Tire Pressure Monitoring Sensors (TPMS) that are within the wheels. When you change over your wheels, you will need new bands for the new wheels - which are basically huge worm clamps -- to fit the size of the wheel. Then you need to carefully dismount the tires from the old rims so as to not damage the sensors on the wheel. A good tire shop or dealership will know how to do this. The sensors from the old wheels must be swapped to the new wheels, by mounting them on new bands on the new wheels. Figure that the new bands will cost between $25-45 each, depending on where you source them from. Good luck.
