2018 Ford Mustang Tire Sizes
The 2018 Ford Mustang is listed with four tire sizes: 235/50R18, 235/55R17, 255/40R19, and 265/35R20. The correct size depends on the vehicle’s original wheel and configuration, so use the size specified for your Mustang rather than assuming all versions share one fitment.
The numbers describe tire dimensions and wheel diameter; the final number identifies the wheel size in inches. The listed sizes vary, but the provided facts do not link any size to a particular trim or engine. Check the tire placard on the driver-side door jamb or the owner’s manual to confirm the specification for your vehicle. If the size you need is not listed there, confirm it on the door jamb or in the owner’s manual.
