Spare tires are very important on cars, helping drivers to repair themselves when the main tire has a problem on a deserted road, but why are they usually smaller than the main tire?
Spare tires, also known as spare tires, are often equipped on cars. They are used in case the main tire has a problem while driving on the road. Spare tires are usually placed in the luggage compartment (rear trunk) or outside, mounted on the rear of the car or on the hood.
There are many different tire designs, models and brands on the market. However, spare tires usually come in two types: tires of the same size as the main tire (Spare tire): Because they are manufactured with the same size as the main tire, when replaced in the car, the performance and handling of the car remain unchanged. While moving with a Spare tire, braking and steering are also very smooth.
The second type is a tire that is smaller than the main tire (Donut tire): A tire that is smaller than the main tire when replaced can only be used for about 80km. In particular, drivers need to pay attention not to move at a speed above 80km/h.
