How Long Can a Spare Tire Be Used?
1 Answers
An automobile spare tire can be used for no more than 100 kilometers. A spare tire is not designed for long-term use and should only serve as a temporary replacement while the original tire is being repaired. The reasons are as follows: the four tires have different friction coefficients, ground adhesion levels, and air pressures. Prolonged use of a spare tire can negatively impact the vehicle's braking system, steering system, and suspension system, posing potential safety hazards. It may also cause uneven wear on the other tires in the same direction. Precautions for using a spare tire include: 1. Proper positioning of the spare tire; 2. Protecting the spare tire from oil corrosion; 3. Knowing the spare tire's model; 4. Understanding the spare tire's service life; 5. Using a repaired spare tire on the rear wheels; 6. Paying attention to speed when using a spare tire.
