To ensure road safety, **passenger cars, mixed-use vehicles, and other automobiles intended for the transport of goods** must carry tools for changing a wheel. This is important because, in the event of a flat tire, it is necessary to replace it with a spare to continue the journey safely.

- **Spare wheel**: It is essential to carry a spare wheel in these vehicles. This wheel should be slightly more inflated than the others to ensure its effectiveness in an emergency.

- **Wheel change**: If a tire is punctured, speed should be reduced slowly and the vehicle should be stopped in a safe place. Then, the punctured tire is replaced with the spare. Some vehicles have a space-saver wheel, which allows reaching the nearest workshop, but with limitations on distance and speed.

Therefore, it is mandatory for these types of vehicles to carry the necessary tools for changing a wheel, thus ensuring they can handle emergency situations on the road appropriately.
