Some people have a car tire punctured, and when they go to fix tire, repair shop workers tell them that there is no inner tube in their car.
But many people will find it very strange that our motorcycles have cameras. Why don't cars have cameras?
Now we mostly replace tires of our vehicles with tubeless tyres. The so-called tubeless tires do not mean that there is a vacuum inside car tires, and tubeless tires still need us to pump them up.
Tubeless means there is no inner tube between tire and hub, but clearance between tire and hub still needs to be inflated.
Then why are more and more cars using tubeless tires instead of regular tubes? In fact, advantages of tubeless tires are much greater than conventional tubes.Advantages of tubeless tires
First of all, one of most obvious advantages of tubeless tires is that once a tubeless tire is punctured, leakage process is very long and slow. Once a regular inner tube is punctured, it will be immediately detected and tire will leak completely in a short time.
But after a tubeless tire is punctured, it can take a month or two before we find that tire has been punctured and there is an air leak, greatly reducing embarrassment when a tire is suddenly punctured.
Secondly, the wear resistance and thermal conductivity of tubeless tires is much better than conventional tubes. Since there is no inner tube inside a tubeless tire, thermal friction generated by drag while vehicle is in motion can be quickly removed directly through wheel hub.
At same time, since there is no inner tube between tire and hub inside tubeless tire, structure inside tire is also reduced, and unnecessary damage to entire tire caused by friction between inner tube and outer tire is avoided.Disadvantages of tubeless tires
However, tubeless tires have a big disadvantage, that is, tubeless tires are not suitable for very heavy-duty sites, so some large trucks still use traditional conventional tires with an inner tube.
The difference between a tubeless tire and a conventional tube
So how should we tell if our car is a tubeless tire or a regular tube?
First of all, pay attention to valve of tire, is there a rubber retaining ring directly on hub, if so, then this is a tubeless tire.
Secondly, in order to prevent air leakage, tubeless tire is a single unit, like tires of our bicycles, hubs are arranged one after other. Such tires are ordinary tubes. Because tubeless tires do not use banner wheels.
At same time, most obvious sign that distinguishes tubeless tires from conventional tubes is presence on side of a tubeless tire of a string of English letters TUBEL ESS.Finally
In fact, almost all cars we use in our daily lives use tubeless tires. Only motorcycles and large trucks carrying heavy loads still use traditional conventional cameras.
