2015 BMW Z4 Spare Tire
The BMW Z4, a high-performance luxury sports vehicle, does not typically come with a traditional spare tire. Instead, this vehicle is equipped with run-flat tires, a specialized type of tire designed to resist the effects of deflation when punctured, enabling the vehicle to continue at reduced speeds for limited distances. The rationale is to eliminate the need for a spare tire which saves on weight, thus improving fuel efficiency and freeing up additional storage space in the car. However, if owners prefer to have a back-up option, they can consider purchasing a spare wheel and tire separately. The standard tire size for recent BMW Z4 models is 255/35R19 for the rear and 225/40R19 for the front. It is always advised for owners to consult their vehicle's specific manual or a professional to ensure compatibility when choosing a spare tire size.
2015 BMW Z4 comes with 3 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. Refer to vehicle owner's manual or contact BMW dealership to confirm the correct 2015 BMW Z4 spare tire size.
