Car tires are a combination of organic oils and carbon chains. Over time, with the help of technological advancements, this rubber consumable was equipped with a thread and wire reinforcement fabric to help more durability, endurance and useful life, but this is not the whole story. Car tires are said to be completely perishable and have an expiration date. That is why the exact production date is engraved on the sidewall of the tire so that the buyer knows exactly how much of its useful life the chosen tire has passed. But tire corruption is not associated with mold and smell change, but some of the changes indicate the expiration of the useful life of the tire, which in the long run will cause the car tire structure to weaken and finally disintegrate. At this stage, there is a possibility of the car tire bursting.
🔹 Her life
The useful life of common tires in the automotive industry is only 5 years. As a result, even if the tire is not under the car during this time and has been stored in a dark warehouse, the deterioration of the tire does not stop. The carbon chain that forms the tire and the separation of the organic oil in it happens slowly and makes the structure of the tire fragile.
🔹 Sunshine
Sunlight contains small amounts of ultraviolet rays (UV or Ultra Violet). Although this amount is very small, if the tire is exposed to sunlight for a long time and it gets hot, chemical changes occur in the car tire, which causes the release of oily substances and yellowing of the color of the tire. These chemical changes slowly cause the tire to disintegrate.
🔹 Long -term park
If the car is parked in a fixed place for a long time, the pressure of the car's weight is applied to the tire only in the part connected to the ground. This event changes the circular shape of the tire, as well as the constant pressure it puts on that part of the tire, causing tiny cracks.
🔹 Failure to adjust the tire wind
Not setting the tire pressure at the standard level also causes similar problems. In this way, if the tire air is less than the standard level, it causes the tire wall to collapse and create non-standard pressure in the place of folding and cracking. Also, the pressure higher than the standard also causes the tire to be placed in a state of non-standard permanent pressure and continuous stretching of its wall.
🔹 Air temperature
Usually, tire bursts are more common in the hot season, but why? The reason is very simple. The extreme heat of the air in hot areas of the planet, such as desert cities and areas close to the equator, causes the air inside the tire and the surface of the earth to heat up at the same time, both of which lead to a significant increase in the air pressure inside the car tire and its expansion. Even if you set the tire inflation at the standard level, these extreme temperature changes will increase the tire inflation by several units and as a result it will go out of the standard condition.
🔹 Non -driving driving
Carrying out dramatic movements such as burn out, continuous pulling and braking the car will wear the car tire in a short period of time and prematurely end the useful life of the tire. This issue also makes the surface of the tire tread thinner, making the wall always in contact with the ground narrower, and as a result, the inner air pressure of the tire causes the arch to be removed and wear this surface more and faster.
🔹 The weight and speed of the vehicle
All cars produced in the world have a net weight (the weight of the car alone) and gross weight (the final weight of the car with gasoline, cargo and passengers) as well as a specific speed class. Therefore, one or more tires are recommended for each car by the manufacturer, especially with a specific weight and speed rating and standard air pressure. If you don't use the right tires with the characteristics of the car, fast wear, early fatigue and structural intolerance of the tire at high speed can lead to bursting of the car tire.
🔹 Repaired tires
One of the most common ways to reuse a flat tire is to repair it. There are many ways to repair a punctured tire, but the important thing is that a repaired tire will never play the same role as the first day in terms of speed and weight tolerance.
🔹 Move with tire pensions
Do not use a tire that is too low or punctured. When the tire is deflated or punctured, the weight of the car is placed on the edge of the rim, and this narrow edge acts like scissors and simply tears the tire wall. Driving a car with an under-inflated tire or a flat tire, even for a short distance, can easily damage the tire wall and create cracks in its structure, which increases the possibility of its tearing when it is re-inflated.
