BMW 850i Spare Tire
The BMW 850i series, a luxury sports vehicle, often includes the provision for a spare tire, although its inclusion can vary depending on the model and year of the vehicle. The 850i's spare tire type is typically a compact, also known as a 'donut' spare, designed for temporary use and not for high-speed or long-distance driving. In regard to size, it typically comes in a smaller dimension than the regular tires, usually anywhere from 17 to 19 inches. However, this may differ based on various factors, including the size of the original wheels, clearance within the car's wheel well, or modifications made by the vehicle's owner. Therefore, it is advisable for owners to check the specifications for their specific BMW 850i model.
BMW 850i models manufactured from 1991 to 1992 have tires with overall diameter of 25.3", 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 850i years and trims.
