Wide tires and narrow tires, what is the difference?

No matter how good a car is, if it wants to perform superbly, it will not be able to perform well if it is not equipped with a set of suitable tires. Many car friends previously believed that the width of the tire has a great impact on the vehicle. So, is it better to have a wide tire or a narrow tire? We can only know it after analysis and practice.

Generally speaking, the width of car tires is between 125 and 155 mm for mini cars, between 165 and 195 mm for small cars, and between 195 and 225 mm for compact cars. Those above 225 are usually called wide tires.

From the physics we have learned, the wider the tire, the larger the contact area with the ground, which increases the friction with the ground. This will undoubtedly make the tire's grip stronger, more stable during braking and turning, and smoother driving.

If you think that the wider the tire, the better, then you are wrong! Because the contact area between the crown and the ground is large, the tire noise generated will also increase, and the resistance of the tire will also be greater, and the fuel consumption will also be higher.

Narrow tires are the opposite of wide tires. Narrow tires can make the car faster, with less tire noise and lower fuel consumption.

But the braking performance will not be very good. For example, because of the body of an economy car, the tires are generally narrower. Although this saves fuel, the handling is greatly discounted. This is the reason.

In the daily tire replacement process, tire shops sometimes encounter some car owners who are not satisfied with the size of their original tires and want to change their tires to wider ones. On the one hand, they want to make the car more stable, and on the other hand, they want to increase the overall beauty of the car. Because some models now expand the riding space without replacing the original tires, which makes the car look a bit "big and small feet". Therefore, the desire to change tires is getting stronger. During the visit, the tire business found that many car modification shops have tire modification and upgrading.

However, many experienced tire shop owners do not advocate changing the original tire size. They believe:
1. Because the technology of automobile manufacturers is different, the performance of the automobiles produced is also different. For example, the same 1.6L displacement car will have different acceleration. Some will be faster, while others will start slower. If some cars are not very powerful, replacing a wide tire will not only make the car start slower, but also consume more fuel.

2. If you want to replace tires, you can't just replace one or only the first two, but you have to replace all of them, and the pattern must be consistent. This is also to avoid inconsistent tire wear and is for the safety protection of car owners.

3. Some car owners want to replace their original wide tires with narrow tires in order to reduce fuel consumption. Once they are replaced with narrow tires, they have to consider whether the tires can bear the weight of the vehicle. If the car is large and the tires are small, the tires may burst directly due to "unbearable" when the vehicle is overloaded, which will also cause safety hazards.

Therefore, in the daily process of replacing tires, it is recommended to replace the same model. You can change the brand according to your needs, such as saving fuel, making the tire more wear-resistant, or quieter. This is completely fine. Don't change the tire size blindly. After all, tires are to ensure the safety of vehicle driving. Be sure to pay attention when replacing them!
