Basic parameters:
A wheel includes a lot of parameters, and each parameter will affect the use of the vehicle, so in the modification and maintenance of the wheel, before you confirm these parameters.
Size:
Wheel size is actually the diameter of the Wheel, we often hear people say 15 inches Wheel, 16 inches Wheel such a statement, of which 15,16 inches refers to the size of the Wheel (diameter) . Generally in the car, wheel size, flat tire ratio is high, it can play a very good visual tension effect, but also in the vehicle control stability will be increased, but then there are the added problems of increased fuel consumption.
Width:
PCD and hole location:
Wheel width is also commonly known as J value, Wheel width directly affects the choice of tires, the same size of tires, J value is different, the choice of tire flat ratio and width is different.
The professional name of PCD is pitch diameter, which refers to the diameter between the fixed bolts in the center of the wheel. In general, the big holes in the wheel are 5 bolts and 4 bolts, but the distances of the bolts vary, so we often hear the terms 4X103,5X114.3,5X112. For example, 5X114.3 means that the wheel's PCD is 114.3 mm and the hole is 5 bolts. In the selection of wheel, PCD is one of the most important parameters, for safety and stability considerations, it is best to choose PCD and the original wheel to upgrade the same.
Offset:
Offset, commonly known as ET value, wheel bolt fixed surface and geometric center line (wheel cross-section center line) between the distance, said that the simple wheel middle screw fixed seat and the center of the whole wheel ring point difference, the popular point that is wheel after modification is indented or protruding outward. The ET value is positive for a car and negative for a few vehicles and some jeeps. For example, a car offset value of 40, if replaced with the Wheel ET45, in the visual wheel will be more than the original retracted into the wheel arch. Of course, the ET value not only affects the visual changes, it will also be with the vehicle's steering characteristics, wheel positioning angle has a relationship, the gap is too large offset value may lead to abnormal tire wear, bearing wear, it doesn't even work properly (the brake system won't work properly against the wheel) , and in most cases, the same type of wheel from the same brand will give you different ET values to choose from, comprehensive factors should be taken into account before modification. The safest case is to keep the ET value of the modified wheel the same as the original ET value without modification of the brake system.
Center Hole:
The center hole is the part which is used to connect with the vehicle fixedly, that is, the position of the center of the wheel and the concentric circle of the wheel, the diameter here affects whether we can install the wheel to ensure that the wheel geometry center and wheel geometry center can match (although wheel positioner can convert the hole spacing, but this kind of modification has risks, users should be cautious to try) .
Selection factors:
There are three factors to consider when selecting wheel.
Size:
Don't blindly increase the wheel. Some people to improve the performance of the car and increase the wheel, in the case of the outer diameter of the tire unchanged, the big wheel is bound to fit wide and flat tires, the car's lateral swing is small, improved stability, like a dragonfly skimming water when cornering, gliding past. But the flatter the tire, the thinner the thickness, the worse the damping performance, comfort will have to make greater sacrifices. In addition, a bit of gravel and other roadblocks, tires are easy to damage. Therefore, the cost of blindly increasing wheel can not be ignored. Generally speaking, according to the original wheel size increase one or two number is most appropriate.
Distance:
This means that you can not pick your favorite shape at will, but also follow the advice of the technician to consider whether the three distance is appropriate.
Shape:
The complicated, dense wheel is indeed beautiful and classy, but it's easy to be refused or overcharged when washing your car because it's too cumbersome. The simple wheel is dynamic and clean. Of course, if you're not afraid of trouble, that's all right. Compared with the cast iron wheel in the past, the aluminum alloy wheel, which is popular nowadays, has greatly improved its anti-deformation degree, greatly reduced its weight, reduced its power loss, runs fast, saves fuel and has good heat dissipation, for the majority of car owners loved. Here to remind that many car dealers in order to cater to the taste of car owners, before the sale of cars, the iron wheel to aluminum wheel, but in the price of a heavy increase. So from an economical point of view, buy a car don't care too much wheel material, anyway, can be in accordance with their own style to exchange, the price can also save a sum.
