2018 Ford Expedition Tire Sizes
The 2018 Ford Expedition is listed with three tire sizes: 275/55R20, 275/65R18, and 285/45R22. The size shown for a particular vehicle can depend on its original wheel and equipment configuration, so use the matching catalog listing rather than assuming all three sizes fit every Expedition.
In each designation, the number before the slash is the tire width in millimeters, the number after it is the sidewall height as a percentage of the width, and the final number is the wheel diameter in inches. Check the tire-size marking on the vehicle to identify the size currently fitted.
These are the sizes listed for the 2018 model year; the facts do not break them down by trim or engine. For a fitment figure not shown here, confirm it on the door jamb or in the owner's manual.
