1999 Ford Expedition Tire Sizes
The 1999 Ford Expedition tire sizes listed here are 255/70R16 and 265/70R17. These are the sizes associated with the vehicle for this model year; check the tire-size label on the driver’s door jamb to confirm the correct fit for your specific Expedition.
The numbers and letter in each size identify tire dimensions and construction, while the final number refers to the wheel diameter. The two listings therefore correspond to different tire and wheel combinations. This page does not identify which size applies to a particular trim or engine, so do not assume both are interchangeable or that either fits every vehicle.
Tire equipment can vary by year, trim, or engine, and the listed facts do not specify those applications. If your door-jamb label differs, or you need a size for a particular configuration, confirm it on the door jamb or in the owner’s manual.
