Infiniti M45 Spare Tires
The Infiniti M45 used a 5x4.5" (5x114.3 mm) bolt pattern for all models from 2003 to 2010 along with tire diameters ranging from 26.3" to 26.7" 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 Infiniti M45 years and options. In this case, 125/80R18 and 165/70R17 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 Infiniti M45 spare tire.
