2004 Ford Mustang Tire Sizes
The 2004 Ford Mustang tire sizes listed here are 225/55R16, 245/30R20, 245/35R19, 245/40R18, 245/45R17, and 275/40R17. These are tire-size designations, not a single size that applies to every Mustang. Use the size shown for your particular vehicle when comparing replacement tires, and check that the full designation matches before buying.
The list includes several width and wheel-diameter combinations, so the correct choice can vary with the Mustang’s year-specific configuration or trim. The listed facts do not identify which size belongs to each trim, engine, or wheel package, and they do not provide load or speed ratings. Do not infer a fitment or rating from a similar-looking size.
For the size and specifications fitted to your car, check the tire information on the driver-side door jamb or consult the owner’s manual. If the original equipment size or a required rating is not stated there, confirm it with a qualified tire professional before selecting a replacement.
