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.

BMW Z4 models manufactured from 2003 to 2025 have tires with overall diameter ranging from 24.9" to 26", 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 BMW Z4 years and trims.

Listed below are compact spare tire sizes that can fit some BMW Z4 vehicles based on acceptable tire diameter range of 24.2" to 26.8". Some Z4 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 BMW Z4 spare tire size designated by vehicle's manufacturer.
