2025 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.
2025 Lincoln Nautilus comes with 4 OEM tire size options. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Lincoln dealership to confirm the correct 2025 Lincoln Nautilus spare tire size.
