Infiniti M37 Spare Tire Sizes
The Infiniti M37 has used a 5x114mm (5 x 4.5") bolt pattern for all models from 2011 to 2013 along with tire diameters ranging from 27.6" to 27.7" 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 M37 years and options. In this case, a 145/60R20 temporary spare tire is the recommendation for all applications.
