To determine the correct size for *your* 2000 Lincoln LS V8, you should check one of the following:
* The sticker on the driver's side doorjamb: This sticker lists the recommended tire size and inflation pressure. This is the most reliable source.
* The sidewall of your existing tires: The tire size is printed on the sidewall (e.g., 225/55R17).
* Your owner's manual: This manual should specify the correct tire and rim sizes.
Without access to your vehicle's information, I cannot provide the correct rim and tire size. The information above will help you locate the correct sizes for your specific car.
