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.

那是不是說輪胎越寬越好呢?當然不是，弊端也是有的。因為摩擦面積大了，產(chǎn)生的噪音和阻力就會更大，就會產(chǎn)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.

窄輪胎

Narrow tire

輪胎窄了自然加速就會有比較輕盈的感覺和發(fā)揮的空間，油耗也比較經(jīng)濟，但是剎車性能表現(xiàn)得就不會太好了。像經(jīng)濟型、緊湊型的車子的輪胎就會比較窄一點，而性能型、豪華型的就比較寬一點。

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，也會有人對輪胎是否越扁越好產(chǎn)生疑問。扁就是扁平比低，低了可以提高操縱穩(wěn)定性和節(jié)省燃油沒錯。但是凡事都有兩面性，扁了，緩沖能力就下降了，舒適性就不會太好，濕滑性能也會下降。一般一些性能跑車會使用低扁平輪胎。

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.

我們要遵從這幾點去更換輪胎：

We have to follow these points to change tires:

要改裝的輪胎，要與原裝輪胎尺寸相同，如果想要更改尺寸，一定知名改裝店進行輪胎的升級，這咨詢一下生產(chǎn)廠商，可能有些車本來動力就不是很好，如果你再改裝成寬輪胎，無形中就提高了油耗，性價比也同時在降低，這樣做就得不償失了。

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.

在更換輪胎時，不要只換單邊或者一條，要更換時，需要整套更換，而且需要是同，同花紋，同尺寸，這也是為大家的出行考慮。

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.

我們要考慮車子的載重問題，如果你覺得自己的車近期油耗高了，想要換成窄輪胎，那我們就應該考慮，如果換成窄輪胎時，我們的輪胎會不會被壓爆?車子的載重是很大的，這一點是我們需要考慮的!

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!

輪胎的寬窄對整車的性能影響可謂是“牽一發(fā)而動全身”，所以在改裝時一定要慎重，講究“和諧”，為自己的愛車選擇合適正確的輪胎。

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.
