Why Can't Spare Tires Be Used for a Long Time?
2 Answers
Spare tires cannot be used for a long time because: if they are not used for a long time, they will gradually age, causing their safety performance to decline sharply. There are many reasons for the aging of spare tires, such as temperature, humidity, and other external factors. Under the influence of these factors, spare tires will naturally be affected. In fact, a spare tire is for emergency use, not for long-term use. Regardless of whether the spare tire is wide or narrow, the manufacturer has special production and usage requirements. Since spare tires are not used for long-term driving on the car and have no wear, a tire without wear is different from a tire that has been worn out. Using a spare tire on the car inherently carries certain safety risks.
Why can't a spare tire be used for a long time? I have to say, this is a big no-no. I remember that year on the highway, I used the spare tire for a few days, and the car felt shaky, especially when turning, the body roll was severe, almost causing an accident. Spare tires are usually designed temporarily—smaller in size, thinner, with poor airtightness, and not full-size. Using them for a long time can cause wheel imbalance, accelerate wear, and once on the highway, they are prone to blowouts, which is very dangerous. Additionally, they are much lighter than regular tires, and the rubber degrades quickly. Prolonged use may damage the axle or shock absorbers. So after that lesson, whenever I have to replace a flat tire with a spare, I immediately drive to a repair shop to fix or replace the tire, avoiding endless troubles. I recommend keeping a tire pressure gauge in the car and checking it regularly. After all, safe driving is the top priority—don’t cut corners and suffer big losses.
