The wider the tire, the larger the natural contact area with the ground, better lateral force tolerance, improved grip, and improved braking and cornering performance, in other words, better driving stability.

那是不是说轮胎越宽越好呢?当然不是，弊端也是有的。因为摩擦面积大了，产生的噪音和阻力就会更大，就会产生高油耗。

Does that mean that the wider the tire, the better? Of course not. There are also disadvantages. Because the friction area is large, the noise and resistance generated will be greater, resulting in high fuel consumption.

窄轮胎

Narrow tire

轮胎窄了自然加速就会有比较轻盈的感觉和发挥的空间，油耗也比较经济，但是刹车性能表现得就不会太好了。像经济型、紧凑型的车子的轮胎就会比较窄一点，而性能型、豪华型的就比较宽一点。

If the tire is narrow, there will be a lighter feel and more room for natural acceleration. The fuel consumption is also relatively economical, but the braking performance will not be very good. For example, the tires of economical and compact cars will be narrower, while those of performance and luxury cars will be wider.

除此之外，也会有人对轮胎是否越扁越好产生疑问。扁就是扁平比低，低了可以提高操纵稳定性和节省燃油没错。但是凡事都有两面性，扁了，缓冲能力就下降了，舒适性就不会太好，湿滑性能也会下降。一般一些性能跑车会使用低扁平轮胎。

In addition, there will be questions about whether the flat tire is the better. Flat is the flat ratio is low, low can improve the handling stability and save fuel, yes. However, everything has two sides. If it is flat, the cushioning capacity will be reduced, the comfort will not be very good, and the wet sliding performance will also decline. Some performance sports cars generally use low flat tires.

我们要遵从这几点去更换轮胎：

We have to follow these points to change tires:

要改装的轮胎，要与原装轮胎尺寸相同，如果想要更改尺寸，一定知名改装店进行轮胎的升级，这咨询一下生产厂商，可能有些车本来动力就不是很好，如果你再改装成宽轮胎，无形中就提高了油耗，性价比也同时在降低，这样做就得不偿失了。

The tire to be refitted should be the same size as the original tire. If you want to change the size, a well-known refitting shop must upgrade the tire. Consult the manufacturer. It may be that the original power of some cars is not very good. If you refit the tire into a wide tire, the fuel consumption will be increased and the cost performance ratio will be reduced at the same time.

在更换轮胎时，不要只换单边或者一条，要更换时，需要整套更换，而且需要是同品牌，同花纹，同尺寸，这也是为大家的出行安全考虑。

When changing a tire, do not only change one side or one tire. When replacing, you need to replace the whole set of tires with the same brand, pattern and size. This is also for your travel safety.

我们要考虑车子的载重问题，如果你觉得自己的车近期油耗高了，想要换成窄轮胎，那我们就应该考虑，如果换成窄轮胎时，我们的轮胎会不会被压爆?车子的载重是很大的，这一点是我们需要考虑的!

We need to consider the load of the car. If you think your car's fuel consumption is high recently and you want to change to a narrow tire, we should consider whether our tire will burst when changing to a narrow tire? The load of the car is very large, which we need to consider!

轮胎的宽窄对整车的性能影响可谓是“牵一发而动全身”，所以在改装时一定要慎重，讲究“和谐”，为自己的爱车选择合适正确的轮胎。

The influence of tire width on the performance of the whole vehicle can be described as "pulling one engine and moving the whole body". Therefore, when refitting, we must be careful and pay attention to "harmony", and choose the right tire for your car.
