If the original 17-inch car wheels want to change to a larger size, such as 18-inch wheels, the corresponding value will be higher. According to the formula, the diameter difference between old and new tires should be controlled at about 3% to ensure driving safety. As a result, optional tires will be wider and have thinner natural sidewalls.
If you don't mind the increase in fuel consumption and think the larger size is more appealing, there are a lot of things you should be aware of when driving after buying. Because the car hub is relatively large, the tire is relatively wide, and the tire wall is relatively thin, so if you do not pay attention, the probability of a bulge or a flat tire will be much higher than that of a small wheel hub. As we all know, the car wheel is an important part of the car.
In order to ensure the safety of the car, it is necessary to choose a good wheel hub. When choosing aluminum alloy wheels, we need to know that their aluminum alloy wheels also have advantages and disadvantages. Aluminum alloy wheels are light in weight, good in heat dissipation and good in appearance, gradually replacing steel wheels.
The basic principle of choosing a wheel hub or wheel cover is that it must be easy to clean and not blindly pursue beauty. When washing the car, the hub or wheel cover with complex structure is very troublesome. It is good to be beautiful, simple and easy to clean.
The black material on the wheels of a car is actually carbon powder, and the brakes all clamp down on the brake calipers. After a long time, due to the constant friction between the two, it will settle down. It should only be covered lightly on the surface.
However, due to the infrequent cleaning and maintenance of the wheel hub, the wheel hub is heated during daily driving, and the toner will slowly accumulate on the surface of the wheel hub. Over time, coking became more and more difficult, and water could not wash it off at all. Every time you brake, the gravity of the car will move forward due to inertia, so most of the weight of the car is pressed on the front wheels, so the burden on the brake calipers increases, and the wear is naturally more serious than the weight of the rear wheel hub.
We all know that less unsprung weight leads to better car performance, better acceleration and braking, and better fuel efficiency. The hollow design greatly reduces the weight of the car hub, and the aluminum alloy also provides sufficient strength for the spokes to support the rim. This is why many car owners want to replace forged wheels.
Because the forged wheels are not only good quality, but also light weight. Of course, the hollow design saves the aluminum alloy material used in the manufacture of the wheel hub, reduces the production cost of the wheel hub manufacturer, naturally reduces the cost, and consumers also enjoy benefits. On average, each aluminum alloy wheel is 2 kg lighter than a steel wheel of the same size, and a five-wheeled vehicle can save 10 kg.
Although aluminum alloy wheels are more expensive than ordinary steel wheels, the fuel cost savings will be enough to offset the cost of driving 20,000 kilometers per vehicle. The impact resistance, tensile strength and thermal strength of aluminum alloy wheels are higher than those of steel wheels. This is also one of the reasons why aluminum alloy occupies an important position in my country's imitation industry and aviation industry.
The precision can be as high as 0.05mm, and the balance performance is good, which is beneficial to eliminate - in addition, the general body length and steering wheel vibration. If the aluminum alloy wheel is broken, in order to save costs, you still go to some unprofessional places for repairs, then you are very wrong, so the repaired wheels are not guaranteed.
In fact, many places are reworked by the original factory process, and the airtight test, grinding, painting and other processes can be reworked. If you're concerned about safety, the hubs are also cast from an aluminum alloy solution during the casting process. Similarly, the welding is carried out by means of internal and external welding, and the same aluminum alloy material is used, so there is no need to worry about quality problems.
