Cars often do not have full-size spare tires to save space and reduce weight, which helps improve fuel efficiency and vehicle performance. Compact spare tires, or 'donuts,' are lighter and take up less trunk space, offering convenience without significantly impacting the car's design. While a compact spare is intended for short-term use, it provides a practical solution for temporary emergencies, allowing drivers to safely reach a repair facility without the burden of carrying a full-size spare.
