2018 Infiniti QX30 Spare Tire
The Infiniti QX30, a luxury compact crossover produced by the Japanese automaker, has a compact-sized spare tire known as a temporary mobility kit or "donut" located in the trunk compartment for easy access during roadside emergencies. This spare tire is specifically designed for temporary and lower-speed mobility, allowing the driver to proceed to a service station or dealership for necessary tire repair or replacement. The size of the spare tire varies depending on the year and trim level of the Infiniti QX30. In most cases, the spare tire might not have the same diameter and width as the regular tires, and it is not meant for long-distance driving or high-speed operation. Exact size details can be found in the vehicle owner's manual or on the tire's sidewall, but it's commonly known that this compact spare tire has limited capability and should be replaced with a full-size tire as quickly as possible.
