Genesis G90 Spare Tire

The Genesis G90 doesn't come with a traditional spare tire; instead, it is equipped with a Tire Mobility Kit (TMK). This kit includes a small air compressor and a can of tire sealant which is used to temporarily patch a tire puncture, allowing the driver to reach a service station for further assistance. However, if a G90 owner prefers a traditional spare tire, it will need to match the standard tire specifications. The G90 base model uses 19-inch P245/45R19 tires on the front and P275/40R19 on the rear, while the ultimate trim uses 20-inch P245/40R20 at the front and P275/35R20 on the rear. Therefore, the spare tire required will have to match these sizes, respectively, depending on the model to ensure compatibility. It's always recommended to consult with Genesis customer service or a knowledgeable tire specialist before purchasing a spare tire.

Genesis G90 models manufactured from 2017 to 2025 have tires with overall diameter ranging from 27.7" to 28.7", 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 Genesis G90 years and trims.

Listed below are compact spare tire sizes that can fit some Genesis G90 vehicles based on acceptable tire diameter range of 26.9" to 29.6". Some G90 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 Genesis G90 spare tire size designated by vehicle's manufacturer.
