Car owners who have exploded tires in the car should find a phenomenon: most of the car spare tires are small than normal tires，And most of the color is bright，Why is this? Dedicated spare tires are also called non -full -size spare tires，The biggest difference compared to the normal use of tires and normally used tires is that the specifications and size of the tires are smaller seabet iothan the normally used tires。If one of the tires burst into a special spare tire, the vehicle can only drive at low speed。So，The question is here，Why does the manufacturer make the spare tires the same size as the factory tires?

Roughly these reasons:

1. Reduce cost。The cost of this spare tire is cheap，Manufacturers can also save money。You must know that if you change the non -full -size spare tire, the price includes the entire wheels is about hundreds of yuan，More cheaper than full -size spare tires。

2. Small size，Small space。Because the size is small，The thickness of the tire is thin，Basically does not take up space for trunk。

3. The weight is relatively light，Simple installation。Non -full -size spare tires are small，Light weight，Compared with full -size spare tires, it can be much easier，It is not so laborious when installing。But the whole process of changing spare tires is still very troublesome。

4. More importantly，It will remind the owner，Don't use spare tires as common tires，To replace normal tires as soon as possible。

Can full -size spare tires be used as normal tires?

Some cars on the market are also equipped with full -size spare tires，Many friends will ask，Can the full -size spare tire be used as normal tires?

The answer is:Not。

The consistency of the size does not mean that all other parameters are exactly the same，For seabet appexample, the speed level of the tire、Load Index、Tire pattern, etc.。Another，The original wheel hub is mostly aluminum alloy material，and spare tire wheels are mostly steel，This will lead to the weight of the spare tire、Heats、Wind movement, etc. are inconsistent with the other three standard tires，Long -term use，It will lead to uneven duration.，This will also lead to the unbalanced driving of the car，Long -term use of safety hazards。

So spare tires are spare tires，The role of spare tires is just to cope with temporary tires that cope with the emergency situation。No matter whether the spare tire is full size，It is recommended to use temporarily，Pay attention to the limit of driving speed。
