What to Know About Tire
Undoubtedly, tires are the most important parts of the vehicles. But do you know which tire is the most suitable in terms of vehicle and driving conditions or do you know enough about this most important part of your vehicle? As AKO News magazine, we will share with you a few important information about the tire this month.
Is “Four Season Tires” Summer Tire Counted?
It should be known that M + S "All Season Tires" which do not bear the "Winter Tire" symbol will not be a good winter tire in winter and a good summer tire in summer.
1-How is the winter tire different from the summer tire?
As the material of the summer tires hardens at temperatures below 7 ° C, the adhesion to the road decreases. In addition to the special profiles of the winter tires, the Silica based material they are produced is softer and increases the retention in dry asphalt, snow and ice in cold weather conditions below 7 ° C.
2-Does nitrogen gas pressed on the tires cause problems?
No. As it is known, the air we press on our tires under normal conditions is gases in the atmosphere. There are 78 percent Nitrogen, 21 percent Oxygen and a small amount of other gases in the atmosphere. Oxygen gas, which is 21 percent, condenses inside the tire after a while and as a result of this condensation, fatigue occurs inside the tire. Since nitrogen gas (nitrogen) is a drier gas, these fatigue is much less than using normal air and the tire's service life is extended. In addition, since nitrogen gas expands less, pressure changes in the tire decrease. In this way, the tires are worn properly.
3-What should we consider when changing tire size?
Many examinations are made while determining the tire sizes of the vehicles. Many factors such as the pressure applied by your car on the ground and ground clearance are taken into consideration. When changing the size, we can not only apply the dimensions we want to provide a more beautiful appearance in the vehicle. We should choose the size closest to the total diameter of the tire. We can achieve this by looking at the tables determined by the companies. In its simplest form, we change the height of the center of gravity as a result of attaching a tire of our own size. This can cause serious problems in the handling of the vehicle. When we want to do such a process, we need to apply the dimensions in the user manual of our vehicle or make use of the lists in the tire companies that do this professionally.
4-Why shouldn't the wick be thrown into the flat tire?
When we go to the tire to have the flat tire repaired, a misapplication is made, such as using roving during repair. Although there are still many tire makers doing this practice, today tire manufacturers never recommend wicks in repairing a flat tire. The roving causes balancing in the tire and, more importantly, since there is no healthy patch, it both misses the air inside the tire and causes sudden lowering of the tire due to this leak in the course of the ride. Tire manufacturers recommend mushroom patches in case they can cause fatal accidents.
5-How long will the tires last?
The figures given by the tire manufacturers are between 40,000 km and 50,000 km, but apart from the road covered by the tire, the tire also has a lifetime. On each tire, there is the serial number and production date, which we call the DOT number. At the end of this number is a four-digit number. For example, if there are 2206 numbers at the end of the DOT number, it states that 06 tires were produced in 2006 and 22 were produced in the 22nd week of 2006. If your tire is more than four years old, it means it cannot be used because the tire hardens over time and capillaries develop. While the tires are driving on the road, they gain a heat due to friction, and as a result of this heat, some expands. These cracks on the aging tire may cause splitting due to expansion. For this reason, it is necessary for safety to renew the tires between 40,000 km and 50,000 km and within four years.
6-Can the tire be polished with soap?
Every user who loves their car wants their tires to look black and shine like in the showroom after washing their car. For this reason, he applies chemicals such as arapsab or dishwashing detergent to the sidewalls of the tires. However, such substances lead to the formation of capillary cracks on the tires over time. Instead of such applications, manufacturers recommend the use of well-known brands, special care and polishing foams for tires.
7-Is the patch bursting from the sidewall?
Tires consist of parts like sole, cheek and heel and the weakest area among them is the cheek part. Rough pits cause the tire to wear off the pavement before the road starts yet. In such blows, the most damaged part is the cheek (ballooning, splitting, etc.). Tire manufacturers do not
