Can a Spare Tire Run at 100 km/h on the Highway?

[DeJames]

Automobile spare tires are divided into two categories: full-size spare tires and non-full-size spare tires. If it is a full-size spare tire, since the size of the original tire and the full-size spare tire are the same, there will be no restrictions on the mileage and speed of the vehicle using the spare tire, and it can run at 100 km/h on the highway. However, if the spare tire is a non-full-size spare tire, the driving speed should not exceed 80 km/h, and when replacing the spare tire, it can only be used on non-driving wheels. For more details, please see the following: 1. The difference between the spare tire and the original tire: The full-size spare tire has exactly the same specifications as the other four tires on the vehicle and can replace any one of the temporarily or completely unusable tires. The non-full-size spare tire has a slightly smaller diameter and width than the other four tires and can only be used as a temporary replacement, and only on non-driving wheels. 2. Additional information: The spare tire is actually for emergency use and is not a tire for long-term use. Regardless of the width of the spare tire, manufacturers have special production and usage requirements. Since the spare tire is not used for long-term operation on the vehicle and has no wear, a tire without wear is different from a tire that has been worn out. Using a spare tire on the vehicle inherently carries certain safety risks.
