There are many traffic accidents caused by car punctures, especially in high-speed sports cars, the survival rate of accidents caused by punctures is extremely low. Then, some people will ask, since a puncture is so dangerous, it’s better to make it solid, and there will be no such thing as a puncture. Is this really the case? I can't see it.
Our car tires are made of rubber, and the operation is to use the elasticity of the rubber carcass to weaken the impact generated when the wheel rotates. If the tires are replaced with solid tires, the cushioning capacity will be greatly reduced, which is not suitable for high-speed transportation vehicles. Moreover, solid tires will damage the road surface and consume much more energy than current pneumatic tires.
The solid tire has no air leakage, and even if the vehicle is overloaded, it will not be deformed. The use and maintenance seem to be very simple. Even if applicable, it can only be used for low-speed and high-load vehicles, such as industrial trucks and power vehicles for cargo.
The role of tires for vehicles is shock absorption, grip, stability, load bearing, etc., which can be said to be a very important component.
Let's talk about the role of pneumatic tires from the perspective of shock absorption. Pneumatic tires can achieve the effect of shock absorption by deforming during operation. To talk about grip and maneuverability, the grooves on the tires will have drainage lines, which can prevent the car from slipping, but if the tires are replaced with solid tires, not to mention the waste of materials, various performance will be greatly reduced.
In general, solid tires have many shortcomings besides eliminating the need to frequently check the tire pressure and other matters, and do not need to be inflated frequently. Therefore, solid tires are not practical, so don't be afraid of trouble and use pneumatic tires.
