2015 Ford Expedition Tire Sizes
The 2015 Ford Expedition tire sizes listed here are 275/55R20, 275/65R18, and 285/45R22. These are the tire-size designations associated with the vehicle; the listing alone does not identify which size applies to a particular Expedition or wheel setup.
The numbers and letters describe tire dimensions and construction, while the final number indicates the wheel diameter in inches. The three listed sizes differ in width, sidewall profile, and wheel diameter, so they are not interchangeable based on appearance alone. This information is specific to the stated model year; the facts provided do not break sizes down by trim or engine, so do not assume that every configuration uses all three.
Check the tire size fitted to your vehicle before replacing a tire. If you need a fitment or rating figure that is not listed here, confirm it on the door jamb or in the owner's manual.
