What to do when a car tire is flat?

[LaElliott]

When a car tire is flat, it is necessary to promptly replace it with the spare tire and drive to a repair center to inflate the flat tire. When driving with a spare tire, it is important to reduce the speed. Car tires are in direct contact with the road surface and, together with the car's suspension system, help protect the vehicle. Symptoms of a flat tire include: 1. The steering wheel becomes heavy; 2. The car becomes unbalanced; 3. The car slows down; 4. There are noises while driving. Tires, commonly referred to as 'che tai' in Chinese, are usually made of wear-resistant rubber materials and can be divided into solid tires and pneumatic tires. Pneumatic tires consist of an inner tube and an outer tire. Generally, manufacturers set the service life of tires at 3 years. If a vehicle is driven 20,000 kilometers per year, it may be time to consider replacing the tires after 2 to 3 years.
