How fast and how far can a spare tire go?
When a tire is damaged, a spare tire is used as a short-term replacement. That means it can't be used to go too far or too fast.
Nowadays, car manufacturers tend to equip a small spare tire instead of providing an identical copy compared to the other 4 tires on the car.
This comes from many reasons such as: Small spare tires help reduce space in the trunk; reduce vehicle weight, save fuel; help drivers easily carry, move and replace; save costs,...
On The Sun, automotive engineering experts from MOTORING have just shared and recommended how far and how fast you can drive when using a spare tire for your car.
Specifically, according to the general rule that most car manufacturers and manufacturers recommend, spare tires should only be used for less than 70 miles (about 112km). If used more, it will be unsafe because this is only a temporary replacement tire, enough for the car to go to a garage for repair.
This comes from the structure when the spare tire is usually much smaller than the standard tire, the steel and polyester layer under the rubber layer is thinner and less durable. Therefore, it is not as durable as a normal tire and is easily destroyed if used for a long time.
The smaller diameter of the spare tire will cause it to bear more force from the weight of the vehicle, and will also cause the axle to tilt. Using the spare tire for a long time can cause some problems with the differential as well as some mechanical parts of the vehicle.
In addition, the speed of the vehicle when using this tire is also very important. Experts say that when a vehicle is using a spare tire, it should absolutely not run over 50 miles/hour (80km/h).
This speed restriction is for safety reasons as spare tires are often much smaller in size and surface area than standard tires, which affects the vehicle's grip and balance, making it very unsafe to drive at high speeds.
Experts also advise that when driving with a spare tire, in addition to paying attention to distance and speed, drivers should also stick to the outside lane with low speed and can turn on hazard warning lights in some cases.
Additionally, some spare tires are labeled as being used only on the front or rear wheels. Therefore, care must be taken to rotate the tires when necessary to ensure proper installation and safety.
