Advantages of widening the rear wheel
The benefits of rear wheel widening are mainly reflected in two aspects. The first point is that it can bring better visual effects. Generally speaking, the wheel hub size of the improved widened tire is between 18-22 inches. The bigger the hub, the smaller the air leakage rate of the tire used. The bigger the hub, the wider and flatter the tire, and the better the visual effect. The second advantage is that it brings stronger grip. The wider the contact between the tire and the ground, the greater the friction and the better the grip. When ESP and ABS are closed, the acceleration of floor oil is not easy to cause tire skid.
The disadvantage of widening the rear wheel is more obvious.
The advantages of rear wheel widening mentioned above are attractive, but it is worth noting that the disadvantages after widening can not be ignored. First of all, it will affect the power of the vehicle. Because the increase of friction will inevitably consume more energy to drive the tire, which is directly reflected in the power decline under the same powertrain. Secondly, the increase of fuel consumption and friction brings greater resistance, and more fuel is needed to drive the operation, resulting in a substantial increase in fuel consumption.
Not only that, widening the rear wheels will also reduce driving comfort. The smaller the flattening ratio, the thinner the sidewall of the tire, the lower the cushioning capacity, and more road vibration will be transmitted to the body, resulting in reduced comfort. In addition, it will also cause abnormal tire wear. In general, normal vehicle tires are not perpendicular to the ground, that is to say, the inclination angle is mostly non-zero. Once the tread width increases, the difference of tire wear between the two sides will be more obvious. The inclination of the rear wheels of some vehicles is fixed and cannot be adjusted later. The most direct impact is that the service life of the rear wheel is greatly reduced. Not only that, you should know that as long as it involves real modification, it will inevitably mean burning money. For ordinary vehicles, widening the rear wheels will also increase a lot of costs.
Ordinary car owners think twice before you act.
Many friends here will say that the disadvantages of widening the rear wheel seem to far outweigh the benefits. Actually, it is. In addition to the enthusiasts in the refitting circle, many car owners who choose to refit the rear wheels are actually blind, neither thinking clearly about the purpose of refitting nor understanding the consequences of refitting. When replacing a wide tire, the matching wheel should be replaced. If it is really to improve the sports performance of the car, the suspension system needs to be upgraded, and the increased cost and risk in the later period are incalculable. So widening the rear wheel seems small, but the impact is really far-reaching. Ordinary car owners must think twice before you act.
To sum up, the advantages of refitting the rear wheel are far lower than the disadvantages, not only many disadvantages. If the owner's car itself does not move, just widening the rear wheel has no practical effect at all. Finally, there is a cliche: refitting is really risky, and into the pit should be more cautious.
