When driving in normal times, you may encounter fever in the
wheels
of the car. Many people may think that the car is damaged or caused by some other reason.This is a very simple question, so don't worry too much.
The reason for its heat may be that the tire rubs against the ground for a long time and then generates heat that will be transmitted to it, and then it will cause its temperature to rise. Another reason is that because of long-term braking, the friction of the brake pads will also produce high temperature conduction to it, causing the temperature to rise.
In fact, this situation occurs because of the heating of the wheel hub. This is a very common and normal phenomenon. You only need to pay a little attention to it. You don't need to enter the repair shop. If the owner is really worried, you can also go to the repair shop to take a look.
It should be noted that in normal times, we must pay attention to its maintenance and repair. If it has some faults but is not found, this is a very dangerous thing. After all, it is used by someone on the car.
The et value of the
wheel rim
is also called the et offset value, and the et value is the offset value, which is the offset.In fact, it refers to the degree of deviation between the rim installation interface and the centerline of the rim. If the et value is greater and becomes a negative value, then it proves that the rim installed on the body will deviate from the outside. So in other words, different et values will affect the wheel track, and the wheel track will affect the maneuverability of the car.
And under normal circumstances, the smaller the value of et, the more the rim will protrude outside the wheel arch.And there are only three degrees of deviation between the interface of the rim installation and the centerline of the rim, one is positive, one is 0, and the other is negative.Among them, the direction to the outside is positive, but the direction to the inside of the rim is negative.And changing the rims will change the wheel track of the car, and the wheel track will affect the distance of the centerline.
So in short, the et value is positive and negative. In most cases, the et value of a car is usually positive. Only a few vehicle models or four-wheel drive vehicles will use negative values. Only off-road vehicles will be installed in the process of use. Copied other vehicles usually install upright wheels.For example, the offset of most vehicles should be et40. If the value is replaced with et45 or et50, then in terms of visual effects, the rim will be easier to enter the wheel arch than the original rim.
Therefore, if you replace it with a rim that is less than the et40 offset value, the visual effect will look more outward than the original rim. This is because the et value is negative, so it can be seen from the visual effect that the rim looks like it is mounted outside the body.
