Now many people haven't got the car, wondering what the other big western hub. In the eyes of the appearance of the party, hub is an important factor to influence the look of the car, not for a satisfactory, I am afraid it is unresolved.
But the wheels to appear to belong to the appearance of components, yet practical and vehicle performance and safety are closely related, if only directed at the nice and cool to change hub. Finally, are likely to outweigh the benefits.
First of all, the wheel hub is not as big as possible.
In the case of the outer diameter of the tire, to change the big wheel must be replaced with a flat tire, so that the car's lateral swing is small, the car will be more stable, too, when the feeling will be more light. Hengding hub said but at the expense of damping performance significantly weakened, a little small bumps will clearly conduction to the inside of the vehicle, comfort absolute to sell at a discount greatly. In addition, flat and thin tire resistance ability is relatively weak, especially in the face of sharp objects on very easily damaged.
For life in cities the majority of people, is not much chance of racing, if purely to the appearance of the wind pull, felling have "stupid". Generally speaking, according to the original car wheel hub appropriate to increase the number one or two is the most appropriate.
Second, not all of the big wheels can improve performance.
Many people think that it is wrong to widen the tire to the big wheel. The size of the tire and the wheel hub will directly affect the inertia of the wheel. If the inertia increases, it can not only affect the acceleration, but also affect the brake. If you want to increase the wheel at the same time a substantial increase in performance, we must try to use a lighter weight wheels.
Hengding hub reminded to pay particular attention to is that under the wheels of the total mass (wheels and tires) the same, hub is larger, the performance will be worse. For example, a 16 inch wheel weight is 30 pounds, a 17 inch wheel weight is 30 pounds, according to the general point of view, the same weight, inertia is the same. But actually not the case, the 17 inch wheels will be more flat tires, and the weight is more concentrated in the outside of the wheel, the high speed rotation, the inertia will be greater, the performance will be reduced.
In this case, the 17 inch wheels will be less than 16 of the performance of the wheel. The only solution is to continue to reduce the weight of the entire wheel, the use of lighter wheels.
Third, the shape of the wheel itself will affect the performance of the car
If a wheel shaped so that the weight is concentrated in a central hub, so when the wheel rotates, the inertia generated is smaller; on the contrary, if the weight of a hub are concentrated in the outer side of the wheel hub, then generates the inertia will. So the wheel hub, not only to look at the total weight of the wheel hub, but also depends on the weight distribution in what position, the weight from the center of the performance of the worse.
Fourth, before changing the wheel hub to confirm the good wheel parameters
A hub includes a number of parameters, and each parameter will affect the use of the vehicle, so in the modification and maintenance of the wheel, the first to confirm these parameters.
1, wheel size: in fact, is the diameter of the wheel, we can often hear people say 15 inch wheels, 16 inch wheels, such a statement, which is 15, 16 inch refers to the size of the wheel hub (diameter).
2, wheel width: wheel width and commonly known as the J value, the width of the wheel directly affects the choice of tires, the same size of the tire, J value is different, the choice of flat ratio and the width of the tire is different.
3, PCD and hole position: PCD professional name called the pitch circle diameter, is refers to the central hub fixing bolt diameter and the general hub mostly hole is 5 star bolt and four bolts, and the distance of the bolt, but also the different, to 5x114.3, for example, is on behalf of the star wheel PCD 114.3mm, hole 5 bolts. In the choice of the wheel, PCD is one of the most important parameters for the safety and stability of the consideration, it is best to choose the PCD and the original car to carry out the upgrading of the wheel.
4 wheel offset: offset, commonly known as the ET value, the distance between the wheel hub bolt fixed surface and geometric center line (wheel centerline cross section), the popular point is hub modification is indented or bulge outward. For the general car, ET value is positive, for a small number of vehicles and some of the jeep is negative. For example, a car's offset value is 40, if change on the ET45 hub, in the visual will than the original hub more shrink into the wheel arches. Et values not only affect the visual changes, it will with the vehicle steering characteristics, wheel alignment angles have a relationship, the offset distance of the gap is too large value may lead to abnormal tire wear, easy abrasion of a bearing, or simply can not be properly installed.
In most cases, the hub with a brand with a style will provide different et values can be chosen, before the modification to consider a combination of factors, the insurance is in do not modify the braking system under the premise, maintain modified wheel et value is the same as the value of the original et Hengding hub said.
And hub center hole: a hole center is used to and vehicle fixed connection part is central hub and the hub concentric position, here the diameter size of the influence to our installation hub can ensure the geometric center of the rim and hub in the geometric center of anastomosis. Although the wheel positioner can change the hole spacing, but this modification risk, cautious trial.
If you change the hub utterly ignorant of such things, or to find the best one brand of professional tire shop to operate it, Albert
