2018 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.
2018 Genesis G90 comes with 1 OEM tire size option. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact Genesis dealership to confirm the correct 2018 Genesis G90 spare tire size.
