BMW i4 Spare Tire
The BMW i4, much like other models from the brand, does not come equipped with a traditional spare tire. Instead, the automaker chooses to utilize run-flat tires that are crafted to maintain functionality for a certain distance even after a puncture, allowing drivers to reach a safe location for repair or replacement. The absence of a spare tire is due to the desire to save space and weight in the vehicle, something of particular importance for the electric i4 model where efficiency is paramount. As for the tire type and size, the BMW i4 typically uses Pirelli P Zero run-flat tires, and the standard size would be 225/55R17 for the front and 255/50R17 for the rear, but the exact size may vary based on the specific i4 model and its package options.
BMW i4 models manufactured from 2022 to 2025 have tires with overall diameter ranging from 26.7" to 27", 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 i4 years and trims.
Listed below are compact spare tire sizes that can fit some BMW i4 vehicles based on acceptable tire diameter range of 25.9" to 27.8". Some i4 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 i4 spare tire size designated by vehicle's manufacturer.
