How fast and how far can a spare tire go?
When a tire is damaged, the spare tire is used as a short-term replacement. That means it cannot be used to go too far or too fast.
Nowadays, car manufacturers tend to equip a small spare tire instead of providing an exact copy of 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 type of tire is only a temporary replacement tire, enough for the car to be able 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 below the rubber layer is thinner and less durable. Therefore, it is not as durable as a regular 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 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 outer lane with low speed, and can turn on hazard warning lights in some cases.
In addition, some spare tires are specified to be used only on the front or rear wheels. Therefore, it is important to rotate the tires when necessary to install them correctly and safely.
