Lincoln Nautilus Spare Tire

The Lincoln Nautilus comes equipped with a compact or 'donut' spare tire designed for temporary use in the event of a tire blowout or flat. The vehicle features an underbody mounted spare tire housed in the trunk beneath the luggage compartment. The spare tire provided is usually smaller in size and narrower than the vehicle's regular tires, which helps conserve space and reduce weight. The specified size for the Nautilus spare tire is generally T155/70D18 (or T165/70D18 for some models), with a rim diameter of 18 inches to match the vehicle's original tire specifications. However, the exact spare tire size can vary depending on the particular model year, so it is recommended to check the Lincoln Nautilus manual or spare tire label located on the driver's door jamb for the accurate size details.

Lincoln Nautilus models manufactured from 2019 to 2025 have tires with overall diameter ranging from 29.3" to 31.1", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Lincoln Nautilus years and trims.

Listed below are compact spare tire sizes that can fit some Lincoln Nautilus vehicles based on acceptable tire diameter range of 28.4" to 32". Some Nautilus models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Lincoln Nautilus spare tire size designated by vehicle's manufacturer.
