How many kilometers can a spare tire run?
2 Answers
Different specifications of non-full-size spare tires have a maximum speed limit of less than 80 kilometers per hour and should not be driven for more than 100 kilometers. Non-full-size spare tires of different specifications cannot be used for long periods and should only serve as temporary replacements during short-term tire changes or repairs. Below are the functions of automotive tires: Supporting the full weight of the vehicle: Automotive tires bear the entire weight of the vehicle, withstand the vehicle's load, and transmit forces and moments in other directions. Enhancing vehicle performance: Automotive tires transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the vehicle's power, braking, and off-road capabilities; they work in conjunction with the vehicle's suspension to mitigate impacts during driving and dampen resulting vibrations. Preventing premature damage to vehicle components: Automotive tires protect vehicle components from severe vibrations and early damage, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and fuel efficiency.
Honestly, I'm quite familiar with spare tires because I've had a few flat tires over my years of driving. A spare tire is just a temporary emergency solution, not designed for long-distance use. It's generally recommended not to drive more than 80 kilometers or exceed 80 kilometers per hour with it. The reason is that spare tires have a different structure: they're thinner, may have insufficient air pressure, and are prone to deformation or wear if used for too long, especially on slippery roads. Once, I accidentally drove 100 kilometers on a spare, and it ended up leaking air, forcing me to call a tow truck. So for safety, try to replace it with a regular tire within 50 kilometers at a reliable repair shop. Also, remember to regularly check your spare tire's storage condition: don't leave it in the car for too many years, as heat can cause the tire to deteriorate. In short, rely on it in emergencies, but don't depend on it too much.
