The tires we see most commonly today are made using some kind of rubber or rubber-like material, but they may use or incorporate of several other materials such as plastic, leather, natural or synthetic fibers, and even steel. A typical passenger car tire in use today is an extremely complex product and may contain over 1,000 individual ingredients.
What a tire does
The most basic, essential function of a tire is to protect the wheel on which it is mounted from wear and tear. Of course there are several other vital functions performed beyond that, such as dampening the vibrations caused by irregular surfaces over which the wheel passes and to enhance traction and control characteristics for the vehicle using them, however, some of these additional functions depend on the type of vehicle and even specific applications in which the tires are used. Examples of this are the differing requirements of tires used on racing cars as opposed to those used on tractors or airplanes.
The contact area of each tire is equivalent to the size of a hand but it can carry the weight of the vehicle and its passengers.
2. Shock Absorption
When driving on unpaved roads, do you know what ensures a comfortable drive? Tires! Tires are formulated using 50% elastic rubber with inner air pressure serving as a shock absorption tool to help minimize bumpy rides.
3. Vehicle Handling, Driving Force, and Braking Power
Tires are the only part of the vehicle that comes into contact with the road. When initiating, driving, braking, or parking your vehicle tires successfully help complete your command.
4. Steering Wheel Movement
Tires communicate the controls of the driver. Steering and reversing operations are dictated by the tires.
Tire Care and Use - Basic Hints
Possibly the most basic tire advice is to keep your inflation pressure right. Next, make sure your tires are balanced, not only when you buy them but throughout their lives. Have your tires rotated regularly and watch for unusual wear patterns which can be signs of alignment defects or other mechanical defects.
