BMW 550i GT Spare Tire

The BMW 550i GT does not come equipped with a typical full-sized spare tire; instead, it utilizes the run-flat tire technology, which permits the car to be driven at a reduced speed for a limited distance even after a puncture. The stock tire size for BMW 550i GT is 245/40R20 for the front and 275/35R20 for the rear. However, the spare tire size may differ depending on manufacturer's recommendations. Some drivers opt for a compact spare or 'donut' spare for emergencies only, which can save space and weight compared to a full-sized spare. Ideally, the best option for a spare tire would be to match the car's original tires to ensure optimal performance and safety, but this should be confirmed with a BMW dealership or trusted tire retailer.
