Infiniti M45 Spare Tire Sizes

The Infiniti M45 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2003 to 2010 along with tire diameters ranging from 26.3" to 26.7" tall. Using a temporary 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. Tire diameter as well as wheel diameter clearance have been taken into account for the specific Infiniti M45 years and options. In this case, 145/60R20 and 165/70R17 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters.
