1991 Porsche 928 Spare Tire
The Porsche 928, a luxury grand tourer produced by the German manufacturer Porsche AG during 1978 to 1995, originally came equipped with a spare tire. This compact, yet highly essential piece of equipment was typically a space-saver type, also known as a "doughnut", designed for emergency use only. The spare tire size for a Porsche 928 usually follows the standard car tire dimension - approximately 165/80R15 or similar depending on the exact model year. These smaller, lightweight spares are not intended for prolonged or high-speed driving, but serve as a temporary fix enabling the driver to reach a place for proper tire repair or replacement. For those wanting a full-size spare, it would ideally match your existing set of tires, but may require additional storage solutions due to larger size.
