2021 BMW i3 Spare Tire
The BMW i3, a plug-in hybrid vehicle, does not come with a traditional spare tire as the manufacturer instead opted to use run-flat tires that can be driven for a limited distance after puncturing. This means there is no dedicated spare tire type or size for the BMW i3. The use of the run-flat tires, which are specially designed to resist the effects of deflation when punctured, allows vehicles to continue to be driven at reduced speeds (under 50mph), ideal for the driver to reach an auto repair shop or roadside assistance. The idea behind this is to eliminate the need for an immediate tire change on the roadside. BMW also provides a roadside assistance service to provide further help in case of a tire issue. Despite the absence of a traditional spare tire, some owners may choose to carry a spare tire kit designed for compact cars or a tire repair kit including sealant and a pump as a precautionary measure. The tire size for a BMW i3 typically ranges around 155/70R19 on the front, and 175/60R19 or 155/70R19 on the rear depending on the model.
2021 BMW i3 comes with 2 OEM tire size options. 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.
