What do you think of the size of the wheels? How much can you understand the size parameters of the wheel hub? Many riders blindly pursue large -size wheels in order to pursue the visual effect, but the choice of the size of the wheel hub is not so casual, it will affect driving safety.Below, lets understand the size of the hub.
How to look at the wheel size
I. The width (J value) of the hub: The width of the tire determines that the width (J value) of the wheel hub refers to the distance between the bumps on both sides of the wheels.The "7.0" in the new wheels refers to 7 inches, and "J" represents the shape and height of the bald edge of the wheels (and the height of C, JJ, JK, K, C is the lowest, and K is the highest).The width of the wheels determines the width of the installed tires. In contrast to the data below, it can be known that the tires with ten wheels and width of this Sagitar champion are the most matched pair.
Second, the wheel bias (ET): Whether the rubbing body determines that the unit of the wheels bias (ET) is MM, which refers to the distance from the center line of the wheel hub to the installation surface.ET comes from German EinpResStiefe, and the literal translation is "pressure in depth."The smaller the distance, the more the wheels will be off the wheels after installation.The bias distance of the new wheels is 54mm, and the bias distance of the small plateau wheels is 51mm. Therefore, the new wheels will shrink in 3mm in the future.The distance determines whether the wheels are friction with the vehicle component. If the spacing of the new wheels is larger than that of the original wheel, or if the width is too large, the friction vehicle suspension system may occur.In this case, we only need to install the pad to reduce the pulp bias to solve the problem.After understanding the data of "7.0J × 17h2 ET54", dont rush to put the wheels on the car first, and there are special attention to pay special attention.
Third, the center hole of the wheels: whether it is stable to decide this is better to understand, that is, the round hole in the center of the wheel hub.The size of the center hole of the golf 6 wheels is 57.1mm. When we choose a new wheels, we must refer to this value: the wheels larger than this value must be added to the car bearing shaft head stably, otherwise the direction will tremble.So what about the wheels smaller than this value? No need to ask, it is naturally impossible.
Fourth, wheel hole distance (PCD): Whether it is installed by it to determine this parameter to understand it.Taking Golf 6 as an example, its hole distance is 5 × 112 — 5 means that the wheels are fixed by 5 screws, 112 refers to connecting the center point of 5 screws into a circle, and the diameter of the circle is 112mm.If the hole distance does not match the data of the original car, it will not be remedy what to install the pads and the ring. If you really encounter this situation, you can only blame yourself without consideration.Fortunately, the ten wheels of the Polish -producing Sagitar champion also belong to the ranks of the original accessories of the Volkswagen. It is definitely appropriate to install it on Xiaogao, which saves a lot of time for conversion parameters.If you want to buy non -original wheels, you cannot be lazy when you treat the parameters mentioned above, otherwise you will only embarrass yourself.
Wheel hubs are one of the most common vehicle modification components. The modified wheels are or low -key or low -key, or luxurious or simple, all show the personality of the owner.The wheel modification is generally the most suitable according to the size of the original car hub. If you pursue the visual effect, you will blindly pursue a large -size wheel hub and a large flat ratio, which will affect driving safety.
Wheel size parameter
"If the wheels are large, the tires are higher than higher than the visual impact, and due to the widening of the tire, the ground area increases, and the driving is more stable, but the fuel consumption also increasesUnderstand the value on the hub, including size, width, E T value, PCD and hole positions.The size of the wheels is the diameter of the wheel hub. The 15 -inch wheels of the 15 -inch wheels and the 16 -inch wheels refer to the diameter of the hub.The J value that is commonly known as the wheel hub is directly affecting the choice of the tire. The same size of the tires have different J values. The flat ratio and width of the selected tires are different.
The ET value is the difference between the fixing seat of the middle screw of the wheel hub and the center point of the entire wheel."Under the premise that the brake system is not modified, the ET value of the modified wheel is the same as the original ET value." Master Huang pointed out that the ET value is related to the steering characteristics of the vehicle and the positioning angle of the wheel positioning.The distance value may cause abnormal wear of the tire, the bearing is easy to wear, and even the unable to install it normally at all.
PCD and holes are one of the most important parameters of the wheels. Among them, PCD refers to the diameter between the fixed bolt in the center of the wheel hub.Most of the ordinary wheels are five bolts and four bolts, but the distance between the bolts is different.Taking 5 × 114 as an example, the PCD of the wheel hub is 114 mm and five holes bolts.In order to consider security and stability, it is best to choose a wheel that is consistent with PCD as the original car for upgrading and modification.
Is the wheel modification bigger the better?
It is most suitable to increase one or two numbers according to the size of the original car hub.In order to pursue stronger visual impact, more fashionable dynamics and beauty, they blindly pursue large -sized wheels and large flat -ratio tires. This will reduce comfort, increase fuel consumption, and even affect driving safety.In order to improve the performance of the car and blindly increase the wheels. Although the stability is improved, the flatter the tire, the thinner its thickness, the worse the shock absorption performance, and the comfort of the comfort, and it is more likely to damage.There is also the hole distance, screw eye distance, eccentric spacing, etc., must be suitable for the original model, rather than picking your favorite shape as you want.
