How Long Can a Car's Spare Tire Be Used?
1 Answers
A car's spare tire can be used for two to three days. It is not advisable to use a spare tire for an extended period because the parameters and material of the spare tire's rim differ from those of a regular tire. This results in differences in weight and heat dissipation performance, which can pose safety risks if used long-term. The purpose of a spare tire is to support the vehicle in emergencies, allowing it to be driven to a repair shop. Once the regular tire is repaired, the spare should be replaced promptly. Some non-full-size spare tires, in particular, can easily cause the car to pull to one side, and prolonged use may affect the wear of the regular tires. Since spare tires are stored for long periods, their wear differs from that of regular tires, making sudden braking more likely to cause skidding.
