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.
There are many parameters involved in replacing the wheels. It is best for interested owners to do their homework first so as not to cause hidden dangers to safety.
1. Center Bore (CB)
Refers to the size of the center hole of the hub.Although wheels with different values from the original factory can be installed through positioners, this is not recommended for safety reasons.
2. Section circle diameter (PCD)
For example, a hub with a diameter of 5x120mm means that it has 5 positioning bolts, and the diameter of the circle they form is 120mm.This value should also comply with the original factory.
3. Offset
Also known as the ET value, this value is positive, indicating that the fixed surface of the hub is outside the center surface, and vice versa, it is within the center surface.The deviation value of a car is generally positive, and this value has a great impact on the stability of the car and the traceability of cornering. It is determined by the original factory and cannot be changed without special needs.
4. Diameter and width
The diameter determines the size of the
rim
.Since the speedometer reading of the car is measured based on the speed of the wheel, the wheel diameter is too large to cause the speedometer reading to be too small. Unknowingly, you are speeding.Excessive wheel diameters will also rub against the wheel arches and fenders.Therefore, it is better to upgrade the wheels to be 1 inch larger than the original factory, no more than 2 inches at most, and to match thin tires to ensure that the size of the entire wheel is the same as before the upgrade.
The width affects which tires are selected after the upgrade. Tires that are too wide will reduce the starting speed and consume more fuel.The correspondence of common values is: 185mm wide tires correspond to 5-inch wide rims; 195mm corresponds to 6 inches; 205mm corresponds to 6.5 inches; 215 corresponds to 7 inches.
1. Select a suitable cleaning agent.
Household cleaners and common detergents on the market are more alkaline or acidic and more corrosive to the wheel surface. To avoid contact with strong chemicals, choose neutral soapy water to wash your wheels.
2. Do not wash the wheels when the temperature is too high.
When the temperature of the wheel rim is high, please do not directly wash it with cold water. Please wait until cool before washing. Otherwise, the
alloy wheels
will be damaged and the brake disc may be deformed. affect the braking effect. In addition, washing the aluminum alloy wheel with washing powder at high temperature will cause a chemical reaction on the surface of the wheel, lose its luster, and affect the appearance of the wheel. When cleaning aluminum wheels, use a sponge or towel. Please don't use too hard wool brush. Using a steel wool to remove stubborn stains can damage the surface of the wheel.
3. Clean the rim properly.
If there are hard-to-remove stains on the surface of the wheel rim, a professional cleaner should be used to remove the stains gently and effectively to reduce the damage to the surface of the aluminum alloy. When the car has been used for a certain period of time, when a hard, dark brown coke layer forms on the wheels, a cleaner is needed. If the rim is soiled with hard-to-remove tar that general cleaners won't do, use a brush to remove it. However, please do not use too hard brushes, especially iron brushes. It is easy to damage therim surface.
The car is in a wet or near coast. To prevent the aluminum surface from being corroded by salt, the wheels need to be washed frequently. After washing as needed, apply wax to the rim to keep it shiny.
4. Develop good driving habits.
Car owners should pay attention to lower road obstacles in daily driving, and do not park too close to the roadbed. In this way, the rim is easily damaged, and the appearance and rust of therim are also prone to occur. Removal of waterproof coatings that affect waterproofing and corrosion resistance. This will deform therim and affect driving safety.
