2003 Ford Mustang Tire Sizes
The listed tire sizes for the 2003 Ford Mustang are 225/55R16, 245/30R20, 245/35R19, 245/40R18, 245/45R17, and 275/40R17. These are tire-size designations, not interchangeable recommendations; match the size shown for your specific Mustang before buying replacement tires.
The list includes several different wheel diameters and tire widths, so the correct fit depends on the vehicle’s original equipment and configuration. The available sizes may vary by year or trim, but the facts provided do not identify which size belongs to a particular trim or engine. Do not assume every listed size fits every 2003 Mustang.
If your vehicle’s required tire size is not clear from this list, confirm it on the driver-side door jamb or in the owner’s manual. Use those vehicle-specific references rather than selecting a size based only on this general list.
