“From the shallower to the deeper、Step by step” is one of the efficient strategies for learning knowledge。In the first two columns，We have a preliminary understanding of the meaning of tire side markings、Internal structure、Maintenance precautions and winter tire characteristics，So this column will introduce other knowledge about tires in detail，Including main tire types and performance comparison、In-depth maintenance items and analysis of common abnormal tread wear。As the saying goes, "Know yourself and know the enemy、A hundred battles with no danger”，This information will enable car owners to face the temptation of various tire products and maintenance projects，More wisdom，Of course, it will also give car owners a deeper understanding of tire knowledge，Enjoy car ownership life more calmly。

Planning strategies: comparison of main tire types and performance

The power to move forward comes from your feet，Tires are to vehicles what shoes are to people，Tires are the only part of the vehicle that is in contact with the ground，Providing support for every step of the vehicle’s journey。Of course the road is different，The choices are also different，For example, running shoes on a rubber track、Basketball shoes on the wooden floor、Football shoes on the green field、Skate shoes on the cold ice、Hiking shoes on rocks, etc.，This directly shows that，Only adapt measures to local conditions，Only in order to be down-to-earth。Actually，The same goes for vehicle tires。Let’s take a look at the main types of tires and their performance comparison。

Seabet

All-season tires are suitable for cars、Wagon and MPV models，is one of the most common tires，Balanced performance，Combines the advantages of multiple tires，Special material formula can make the tire have better grip and drainage performance in different climate conditions in four seasons，And has good wear resistance。At Seabetthe same time，The hybrid tread pattern design helps the tire cope with dry conditions、Wet pavement and light ice、Snowy road。For those car owners who don’t want to change tires as the seasons change，Using all-season tires is ideal。

However, "skills have specializations"，Although all-season tires can handle roads in a variety of climate conditions，But if the car owner wants to obtain more outstanding tire performance in some aspects，Only the corresponding tire type can be used。For example，Sporty tires significantly improve handling，Silent tires can further improve quietness and fuel economy，Winter tires can effectively deal with harsh ice and snow roads。

All-terrain tires

All-terrain tires are mainly used in SUV models，Emphasis on dual adaptation to paved roads and non-paved roads。Because it is different from a hardcore off-road vehicle that only drives in the wild，SUV models are more popular on urban roads，So all-road tires cancel the block pattern used in off-road tires，Switch to directed patterns，Conducive to improving comfort on paved roads。At the same time，Lower aspect ratio、Slightly softer materials and thicker sidewalls help all-road tires obtain better grip on bad roads。

But “you can’t have your cake and eat it too”，When facing extremely harsh off-road conditions or harsh ice and snow roads，All-terrain tires must face the problem of weak off-road capabilities，It is wise to replace off-road tires or winter tires at this time。

Silent tires

Silent tires are mainly used in economical cars。This kind of tire is designed to pursue good quietness，Generally in the tire pattern、Trench、Improvements in material and structure，And often have good fuel-saving performance。First，In order to reduce the noise generated by the squeezing process of the air in the tread pattern when the tread contacts the ground，The tread patterns of silent tires have an unequal spacing design；Secondly，The spacing and number of longitudinal grooves are increased at the same time，To reduce the tread contact area；Again，Add appropriate amounts of silicon into tire rubber，To increase material hardness，Reduce tread contact area；Last，Vibration-absorbing seabet myrubber is generally added under the tread，To reduce vibration and noise。

But "Every gain must be a loss"，The harder carcass of silent tires has poor adaptability to bumpy roads，Easy to increase body vibration，Also，The smaller contact area affects the tire grip，Has a negative impact on vehicle handling。

Low pressure continuation tire

Low-pressure continuation tires are also called run-flat tires，Commonly known as "run-proof tires"，Except for some car brands that apply it to all models，Low-pressure continuation tires are generally used in a small number of sports car models。This type of tire has thickened rubber sidewalls and high heat-resistant synthetic rubber material。Even if this tire loses air pressure，The side walls can also support the weight of the vehicle，Will not cause severe deformation，So in general，After deflation, it will not seriously affect the driving of the vehicle，Can still travel a certain distance at low speed。The wheel hub is specially designed，The outer edge ridge prevents the tire from detaching after a sudden drop in pressure，To improve security。

In fact, low-pressure continuous tires inevitably lose sight of one thing in terms of overall performance，Due to the thick sidewall、High hardness，Not only requires professional installation and construction，And it will also affect vehicle comfort due to poor vibration damping，This is one of the reasons why most high-end luxury cars do not use low-pressure continuation tires。

Sports tires

Sports tires are usually used on sports cars or other vehicles that emphasize sports performance，Focus on achieving maximum grip on standard paved roads，hence extremely low aspect ratio、Soft material、Special tread coverage and solid shoulder design are its main features。where，Special tread cover with non-uniform tension design，Can tightly grip the middle of the tread，Effectively inhibits the bulging deformation of tires caused by centrifugal force at extremely high speeds，Thus maintaining the maximum tread contact area。The solid tire shoulders can provide sufficient lateral support for the vehicle to turn at high speed。

But "football has its own length"，A little short”，The larger contact seabet ioarea of ​​sports tires brings unsatisfactory fuel consumption and noise，And the higher product selling price and wear rate also increase the cost of use for car owners。

Evaluation description: Comfort refers to tire vibration reduction、Quiet level，Sportiness refers to the level of high-speed handling of tires，Off-road performance refers to the tire's adaptability to non-paved roads，Weather resistance refers to the tire’s adaptability to road surfaces under different climatic conditions，Economy refers to tire purchase cost、Loss rate and fuel consumption level。

Okay, let’s stop here today，About a deeper tire analysis，Please continue to pay attention。
