Knowing the basic knowledge of tires is only the first step. The next step is to consider how to buy tires that suit your car. When choosing, in addition to knowing the tire size your car needs, you should also pay attention to the following aspects.
First of all, give priority to the original tires, which can best match the speed and maximum load of the car. Therefore, in theory, tire replacement should be given priority.
Second, pay attention to the tire pattern. The patterns on automobile tires not only have aesthetic effect, but also have great influence on tire performance. Cars that often drive in Shenzhen should choose those patterned tires with good drainage, such as regular small patterns; For cars that need cross-country and long-distance running, you can choose large patterns.
Finally, if you are not satisfied with the original handling of the vehicle, you can consider replacing the tires with lower flattening rate. For many models, one of the most effective ways to improve the appearance and handling performance of vehicles is to replace the tires with low flattening rate. Each type of tire has its specific function, so when choosing a tire, you should ask what type of tire is suitable for what kind of driving habits, so that the car is safer when driving and the money spent on tires is more worthwhile.
When buying tires, don't just look at the price, ask professionals who will help you match the right tires accurately.
When choosing tires, we should also be careful not to mix different types of tires, such as putting tires suitable for off-road vehicles together with ordinary cars, or mixing tires for directional sports cars with ordinary tires.
Of course, try to avoid retreading tires when buying. At present, Shenzhen, especially some street shops, often sell some refurbished tires as inferior products, so consumers must pay attention when purchasing. The way to identify a retreaded tire is simple: the most common way is to observe the color of the tire. Refurbished tires are dull in color, so don't buy such tires blindly.
Professional masters identify tires by the marks on them. There are some protruding marks on the car tires, indicating the model and performance of the tires. These are the breakthrough points in identifying retreaded tires. The signs of retreaded tires are re-attached after retreading, and these signs of brand-new tires are integrated with the tires. The identification method is to scrape these signs with your nails. Generally, these signs of retreaded tires are not tightly affixed, and what can be caught must be retreaded tires.
In recent years, the development trend of foreign car tires is to use more and more tires with large width, large inner diameter and low flatness. At present, domestic cars mostly use tires with small width, small inner diameter and high flattening rate. The tire with high flattening rate has long sidewall, strong cushioning ability and relatively high comfort, but it has poor feeling on the road surface and weak lateral resistance when turning. On the other hand, tires with low flatness and large inner diameter have short sidewalls and wide treads. Therefore, the ground contact area is large, the tire can bear great pressure, it is very sensitive to the road surface, and the lateral resistance is strong when turning, which greatly enhances the handling of the vehicle. At present, the largest flat tire used in domestic production cars is 225/55R 16, while the tires of many imported luxury cars or sports coupes reach 225/45R 17, and some even reach 245/40R 18. After the vehicle is equipped with tires with large width, large inner diameter and low flattening rate, in addition to strong maneuverability, the visual effect of the appearance also gives people a very powerful feeling. Generally speaking, the tires equipped with vehicles are the best specifications selected by manufacturers after repeated tests. If the owner wants to change the tire size, he must do it under the guidance of professionals, and he can't do it at will, because it involves many problems, and a little negligence may cause harm to driving safety. In addition, the low flat tire will be more "delicate", so we should pay more attention and care during use.
