Lincoln Aviator Spare Tire Fitment Guide
The Lincoln Aviator used a 5x4.5" (5x114.3 mm) bolt pattern for all models from 2003 to 2026 along with tire diameters ranging from 29.5" to 31.0" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Lincoln Aviator years and options. In this case, 155/90R18 and 175/90R18 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Lincoln Aviator spare tire.
