Infiniti Q50 Spare Tire

The Infiniti Q50 does not come equipped with a traditional spare tire, instead it is equipped with the run-flat tires, which allow the vehicle to be driven for a limited distance even after a puncture or significant loss of pressure. However, in case of tire replacement, the size recommendation for the Infiniti Q50 is typically 245/40R19, however, the size varies by the year and model of the vehicle. Thus, it's advisable to check the vehicle's owner's manual or consult with a tire professional to guarantee the exact fit. Moreover, many Infiniti Q50 owners decide to purchase a full-size or donut spare tire as extra precaution, even though it sacrifices trunk space.

Infiniti Q50 models manufactured from 2014 to 2024 have tires with overall diameter ranging from 26.7" to 26.9", allowing the use of a temporary spare tire with a near same diameter as the OEM tire. Tire diameter and wheel diameter clearance have been taken into account for the specific Infiniti Q50 years and trims.
