The past, present and future of the tire

The real contact area between the car tire and the ground is actually very small, but it has to shoulder important duties such as load bearing, braking and driving safety. Therefore, its importance is self-evident.


How did the tire develop? In fact, the change of car tires has gone through a long process.


The birth of the first hollow wheel

Long ago, tires were made of wood, iron and other materials.


The first hollow wheel was invented by British Robert Thomson in 1845. He proposed to use compressed air to fill the elastic bladder to mitigate vibration and shock during exercise.


At the time, the material of the tire was leather and rubberized canvas, but this tire has shown the advantage of low rolling resistance.


The emergence of the first rubber tire

The person who makes the wheels really fit on the tires is Dunlop. In 1888, John Dunlop made rubber hollow tires.


At that time, in order to enhance the comfort of the carriage, he put an inflated rubber tube on the wheel of the carriage to reduce the vibration. At this time, Dunlop was just a veterinarian.


Soon after, Thomas made a rubber hollow tire with a valve switch. Unfortunately, because there is no canvas in the inner layer, this tire can not maintain a certain section shape and section width.


Charles Goodyear

In 1834, Charles Goodyear was inspired by coke steelmaking and began testing soft rubber hardening.


After numerous failures, at an accidental opportunity, he found that the vulcanized rubber was not sticky when heated and had good elasticity.


As a result, hardened rubber was born, and the rubber tire manufacturing industry came into being.


The name of the current Goodyear tire is to commemorate Charles Goodyear, the father of rubber.


First batch of car tire samples


In 1895, with the advent of cars, pneumatic tires were widely developed. The first batch of car tire samples appeared in the French Peugeot model this year.


However, the pneumatic tires at that time were far from what we have seen so far. Not only did it have no tread marks, but even the lifespan was short. It was about thirty or forty miles to be overhauled, and the longest was 2,000 miles.


In addition, tires at that time often suffered from falling off, being pierced or deformed by extrusion.


Current tire


Tire


Today's tires are almost all pattern tires, mainly divided into vertical patterns, horizontal patterns and mixed patterns.


F1 racing cars and some early motorcycles use longitudinal-patterned tires, and agricultural machinery uses more horizontally-patterned tires, while civilian cars generally use mixed-pattern tires.


In recent years, due to the increasingly demanding tires in the automotive manufacturing and transportation sectors of various countries, the focus of tire research has shifted to driving performance, safety performance, comfort performance and economic performance.


The general trend of tire development is “three-way”, namely meridian, no tube growth, and low profile. Currently, these features have been implemented on car tires.


Future wheel


Concept tire


Many cars or aircraft in science fiction films no longer have the shadow of wheels. But within a few centuries, humans are unlikely to say goodbye to the wheel.


In fact, the world's tire companies are trying to develop more advanced and more futuristic car tires.
