How many kilometers can a car drive with a spare tire?
2 Answers
When a car is equipped with a full-size spare tire, it can drive for more than 100 kilometers, while a non-full-size spare tire should not exceed 60 kilometers. It is recommended to repair the tire as soon as possible, as the spare tire is only a temporary solution. Additional information: Precautions for using a spare tire: 1. Regularly inspect the spare tire: During routine maintenance or before a long trip, check the spare tire for wear or cracks. If it has worn down to the indicator line, it should be replaced as soon as possible. 2. Do not use the spare tire for an extended period: Due to its infrequent use and different friction coefficient compared to the other four tires, as well as differences in aspect ratio, width, or diameter for non-full-size spare tires, prolonged use can affect the vehicle's braking system, steering system, and suspension system, posing safety risks and causing uneven wear on other tires in the same direction. 3. Avoid storing with corrosive materials: The main component of tires is rubber, which is highly susceptible to erosion by various oils. Prolonged contact with oil can cause swelling and corrosion, significantly reducing the tire's lifespan. 4. Spare tires have a limited lifespan: As rubber products, tires can age over time, typically with an aging period of about 4 years.
I've had several experiences of tire blowouts while driving. After putting on the spare tire, I usually only dare to drive about 70 to 100 kilometers before quickly finding a repair shop to replace it with a normal tire. Spare tires are designed for temporary use only; they're not made for long-term driving. Most are smaller in size with poor load-bearing capacity, and driving too far can easily wear out the suspension system or cause the tire to overheat and blow out. Speed must also be controlled, not exceeding 80 kilometers per hour, as driving too fast can cause the vehicle to shake and affect safety. Additionally, spare tire pressure needs to be checked regularly, measured every six months to ensure it's at the standard value, otherwise it won't be usable in an emergency. Before long trips, I make a point of checking the condition of the spare tire to reduce unexpected incidents on the road. After all, safety comes first, and saving a little money isn't worth it.
