For answer  A 

If the tire has insufficient pressure, the tire deforms permanently, overheats excessively, wears on the edges of the tread surface and cracks appear in the grooves of the profile. Over time it can lead to a tire explosion, but it is not the main cause.

For answer  B 

An excessively inflated tire is very vulnerable while driving. Due to high pressure, impacts, centrifugal forces, as well as temperature, its reinforcement can fail and the tire will explode. Therefore, the main cause of tire explosion while driving is excessive inflation.

For answer  C 

Moderate tire wear does not present a risk of explosion, especially if the tire is used properly.

The recommended pressure is indicated on the inside of the fuel tank flap, on the inner strip of the driver's door, in the vehicle manual, or in the engine compartment. There are two recommended pressure values, one for when the vehicle is loaded to maximum weight and the other for situations when it is loaded to normal weight.

The correct answer is: B
