Infiniti QX50 Spare Tire

The Infiniti QX50 typically comes equipped with a compact spare tire, also known as a donut spare tire, that is specially designed for temporary use in case of a tire failure. These compact spare tires are smaller than the standard tires, allowing them to take up less space in the vehicle. It's crucial to note that these should only be used to drive at moderate speeds and short distances, just to get your vehicle safely to a location where the damaged tire can be replaced or repaired. The exact size of the spare tire can vary between different models and production years of the Infiniti QX50, but usually will specify a size such as T145/80D17 for the compact spare as an example, and it's always recommended to confirm the recommended spare tire type and size as per your specific vehicle's owner manual.

Infiniti QX50 models manufactured from 2014 to 2025 have tires with overall diameter ranging from 27.7" to 29.2", 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 QX50 years and trims.

Listed below are compact spare tire sizes that can fit some Infiniti QX50 vehicles based on acceptable tire diameter range of 26.9" to 30.1". Some QX50 models may require the use of a traditional full-size tire as a spare. To ensure safe temporary mobility in case of a road emergency, always refer to the vehicle owner's manual for the correct Infiniti QX50 spare tire size designated by vehicle's manufacturer.
