About tires

If you are in the shop or tire centre for new tires and repairing your tires, all of the variables in tire specifications and confusing jargon you hear from salesmen might make you feel stressful and confused.

We are talking about tires below and can make you understand more the tires you already have. In the article, you can know how tires are built, what all the numbers and markings on the sidewall of a tire mean, how a tire supports a car, and how important your tire pressure is.

After reading this article , you might not build up a tire, but you can know how to diagnose some common tire problems and maintain your tires.

A tire is made up of several different components: the bead,the body,the belts, the cap plies,the sidewall, and the tread. The bead is a loop of high-strength steel cable with rubber. The body is made up of several layers of different fabrics, called plies. The plies are coated with rubber to help them bond with the other components and to seal in the air. A car’s strength is often described by the number of plies it has. Most car tires have two body plies. Belts made from steel provide puncture resistance and help the tire stay flat so that it makes the best contact with the road. The cap plies are mostly used on tires with higher speed ratings to help all the components stay in place at high speeds. The sidewall provides lateral stability for the tire, protects the body plies and helps keep the air from escaping. The tread is made from a mixture of many different kinds of natural and synthetic rubbers.

All of these components are assembled in the tire-building machine. And this tire is called a green tire. The next step is to run the tire into a curing machine, molding in all of the markings and traction patterns, which is called vulcanizing. After a few finishing and inspection procedures, now, the tire is finished.

To choose a tire correctly for your car, basically, you need to know the meaning of each section of small prinit on a tire’s sidewall. The samll print shows tire type , tire width, aspect ratio, tire construction, rim diameter, uniform tire quality grading etc. these kinds of information. Check out these information on the sidewall of a tire, you know you car is “P”-passanger vehicle tire or “LT” light truck tire. You know which size,”R”-radial consstruction tire or “B” bias belted construction tire need to buy.

You may have wondered how a car tire with 30 pounds per square inch(psi) of pressure can support a almost 2 ton car. This is an interesting question. The next time you get in your car, take a close look at the tires. You will notice that they are not really round. There is a flat spot on the bottom where the tire meets the road, it’s called the contact patch.

You can see that the underinflated/overloaded tire is less round than the properly inflated, properly loaded tire. When the tire is spinning, the contact patch must move around the tire to stay in contact with the road. At the spot where the tire meets the road, the rubber is bent out. It takes force to bend that tire, and the more it has to bend, the more force it takes. The tire is not perfectly elastic, so when it returns to its original shape, it does not return all of the force that it took to bend it. Some of that force is converted to heat in the tire by the friction and work of bending all of the rubber and steel in the tire. Since an underinflated or overloaded tire needs to bend more, it takes more force to push it down the road, so it generates more heat.

The heat can cause problems with tires commonly these situation: underinflation, overinflation and misalignment. Underinflation can cause reduced fuel efficienty and increased heat buildup in the tires. It is important to check the tire pressure with a gauge at least once a month. Overinflation causes tires to wear more in the center of the tread. The tire pressure should never exceed the pressure than the maximum thatis listed on the side of the tire. Misalignment of the wheels causes either the inside or the outside to wear unevenly, or to have r aough, slightly torn appearance.

With this overview of the tire, you can choose the right tires for your car with confidence next time.
