Product Description:

Aluminum alloy wheel is designed for automobile, a barrel shaped metal parts used to support the tyres within the tire profile. The original factory wheel hub on the market can be divided into steel wheel hub and alloy wheel according to the material. Compared with the former, the latter have more advantages. Aluminum alloy wheel is an excellent representative of alloy wheel.


Wheel Aluminium Alloy Model No. 813 for the best quality performance


Size ETCBHoleP.C.DFinish
20X8.53178.16139.7chrome


Product Description:


1) Lighter than tube wheels makes the car much more oil saving.


2) Better cooling performance in longdistance and high speed driving keeps the car safe enough.


3) Bigger external diameter let the driver feel much more comfortable. 


4) High speed lowering tyre termperature can reduce wear resistance prevent tyre-shoulder seperation

Q:Why does the vertical load of the outer wheels be higher than the inner wheels when the car turns?
The roll moment is mainly produced in three parts: 1 Suspended mass Centrifugal force caused by the roll moment 2 after the roll, the mass of gravity caused by the roll moment 3 independent suspension, non-suspension quality caused by centrifugal force.
Q:Why should I lock the inner wheel when I enter the corner?
Because the corner when the focus shifted to the outside of the body, closed grip is insufficient, coupled with the drivers are with the brake into the bend, to F1 as the metamorphosis of a slight mistake will lock the brake
Q:What is the hard drive and pedal hard?
Vacuum is not enough! check! Vacuum assist pump
Q:Vehicle maintenance (wheel bearings)
need
Q:About the specifications of the car wheel
Tire type and specification: International standard tire code, expressed in millimeters as a percentage of section height and flatness, followed by: tire type code, rim diameter (inch), load index (permitting bearing quality code), promise With speed code. For example: 175 / 70R 14 77H 175 represents the tire width is 175MM, 70 means that the flatness of the tire cross section is 70%, that is, the cross section height is 70% of the width, the rim diameter is 14 inches, the load index 77, the allowable vehicle speed is H level
Q:Why the wheel and rail matching hardness of 1.2 ~ 1.4?
The wheel is harder than the rail. At this point, the wheel deformation is less than the track, the wheel and rail contact surface for the surface, creep phenomenon is more obvious, not easy to slip; the other hand, the rail is harder, the contact surface is similar to the plane, wheel and rail easier to slip, and this time the wheel easier to wear to the limit The Creep of the relevant content, refer to Professor Ren Zong's "vehicle system dynamics"
Q:Some sports car wheel why eight-shaped valgus?
Modified air suspension effect, low lying wheel, adjust the tire's camber angle, to reduce the vehicle center of gravity and improve vehicle stability have a certain effect, but also a modified style, North America is more common, the US imperial car some changed very exaggeration. The The
Q:Is circular wheel rolling the most efficient way to move on land? why?
The distance between the center of gravity and the support point in the process of rotation is a constant value - the radius. (In theory, the real life of the wheel can not be absolutely round, the road can not be absolutely flat)
Q:Why do not electric motors drive the wheels directly?
First of all, now, there are some car companies have launched a double-wheel motor-driven electric bus (note that the bus), such as BYD K9, has been running in the streets of Xi'an. But only the promotion of the bus. Four-wheel drive or a small car, are not put on the market.
Q:Maya wheel roll forward mel
First you have to know the wheel's moving distance is 2πr (r is the radius of the wheel, known)
