As an important part of auto accessories, automobile tires can drive cars to move freely. Without it, the car will remain there with a pile of scrap iron. The car must keep the same and synchronized with the four wheels while driving. When changing tires, the car will basically not have four tires replaced at the same time, but two new tires with the same axis, this is why? In the tire replacement process, we need to pay attention to what issues?

Reasons for changing two coaxial tires together

In the process of using cars, most of the time we are changing two wheels together instead of four. The main reason for this is that the owner of the vehicle rarely makes regular adjustments to the four wheels during the use of the car. If the four tires are in an unbalanced condition, they will certainly be subject to the same degree of wear. Therefore, in general, the two tires on the same shaft wear basically the same.

Is a new tire suitable for installation in the front or rear wheel?

According to a senior engineer, if the replacement of new tires is recommended to install in the rear wheel. The new tires that have just been changed are deep and have strong friction. If they are placed on the rear wheels, it is easy to flick the tails when they are turning sharply on wet roads. At the back, the vehicle may be understeering. In general, oversteering requires the owner to reverse the steering wheel, and understeering requires greater efforts to hit the steering wheel. For those novice drivers, the lack of conversion is better controlled, so it is safer to change the new ones.

Editor's Note: There is also a lot of knowledge about changing tires in automobiles. Therefore, maintenance engineers must improve their technical capabilities to understand more in order to make tires safer and reduce losses. When a new tire is on the road, there will definitely be a period of running-in, which will be better after the running-in period.


Gate Valves are called "full-flow" Valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
