What effect does the wheel hub size have on the car?

Automobile hub is one of the most commonly encountered parts in automobile modification. For many friends who like cars, the performance of cars is the beginning of their pursuit of a magical car. However, these cars don't seem to be of much use in daily life. We are not allowed to choose a more useful family car because of different positioning. What is the relationship between the modified large-size rim and the car?

Brief introduction of wheel hub size: large size

Hub dimensions include diameter and width, most of which value the former. Due to the limitation of wheel arch and wheel arch, it is necessary to reduce the flatness after replacing the big wheel hub, ensure that the tire circumference (diameter) is close, and will not destroy the torque, so as to be installed in place smoothly. The biggest advantage of changing big wheels is strong sensory stimulation, but it needs to be matched with wide tires to be useful. Most big wheels will basically increase the tire width or even become negative wheels, and off-road vehicles are used a lot. Secondly, the flat rate of tires becomes smaller, the temperature rise rate is higher at high speed, and the pressure change is smaller, so cars with large wheels, wide tires and low flat rate pay more attention to road performance. On the contrary, off-road vehicles like to use tires with high flatness, even with central air pressure adjustment, so as to climb over vertical walls or decompress through sand.

The relationship between wheel hub size and automobile: the relationship between modified tire and automobile?

The above is the type of modified tire rim. Let's talk about the purpose of modifying the rim first. On the premise of not changing the diameter of the tire, refitting the steel rim tire (which can be understood as factory refitting) will give people a very dynamic feeling in sensory vision, at least make the car tend to move in momentum, and the effect achieved can also make people realize that they will feel more supportive and less inclined when turning.

Widening the tire width and changing the tire diameter will increase the ground contact area of the tire, so increasing the grip of the car has a great relationship with the acceleration, braking and driving stability of the car. If the car accelerates before widening the tire, it will scratch the tire, but after widening the tire, it will shorten this situation and make the power output of the car more direct and effective. Of course, this is an ideal situation. Although the widened tire has brought stronger grip, it is necessary to consider whether the engine power is enough, whether the output shaft can withstand such a strong torque and whether the gear of the axle can withstand such a large stress before modification.

I think it is allowed to change the tire diameter within the necessary range. Some manufacturers will also supply different specifications of tire rims for small partners to choose from. This situation has little to do with the car, but the modification may not be considered thoroughly. The result will be that the tachometer is seriously inaccurate, the fuel gauge is seriously inaccurate, and the mileage will be inaccurate. The change of tire circumference has a great influence on cars, but electronic components can't be monitored.

In short, friends who are interested in automobile wheel hub modification need &; Ldquo, do your best. Try to find the size and specifications suitable for your car and make it more fun for you to play with it.
