Any motorist knows that the road is the main thing - it's security. It depends not only on the driver, but also from his car. Important role in ensuring safety on the road are the Tires. Therefore, their choice should be approached with great seriousness and care. It's no secret that auto shops are full of little variety of tires, and not so easy to choose a reliable tire. In this case, confused even those who have more than a dozen spent behind the wheel. Let's dot the i, and thereby protect themselves and their loved ones, as well as to improve maneuverability of a car.
To get started find out what is the Tires? Tires - a kind of mediator between the vehicle and the road surface. This feature her broker once sharply distinguishes it from other parts of the car. And in this case it appears directly related to safety. At first glance, the Tires is quite simple, but everyone should know that it includes more than 200 materials and consists of about 30 different parts. Tires soften the load on the wheel when the car is moving, as well as to "concatenates" the road surface with the wheels. If all of these functions are performed qualitatively, it provides riding comfort, stability and optimal control of the car.
There are different classifications of tires, but primarily to provide summer and winter tires. Some "experts" also produce all-season tires, but this can not be trusted. Remember, there is no all-season tires, the tire can not be both summer and winter. If you are told that the Tires off-season, it means that it can not perform its functions either in summer or winter.
Tires display their properties not only through the tread pattern, but also through the framework defined by the rubber, etc. Summer and winter tires are distinguished design and chemicals that are part of rubber. As a rule, for the manufacture of winter tires used soft grade of rubber which wears out rather quickly, when you come in the warm dry finish. That's why winter tires are not suitable for use in the summer.
If you choose winter tires, one might ask: take with or without thorns? Here the choice depends on the pavement. To ride in the asphalt rubber suit without thorns, but for country travel a dirt road suitable tires. Winter tires are marked with the word «WINTER».
If you want to buy custom tires, you probably need to change the wheels, the width of the rim is calculated as 0,7-0,75 width of a tire.
Depending on the capacity of vehicle is necessary to distinguish the following types of tires:
- cars;
- cargo;
- for motorcycles, mopeds, scooters,
- for the handling and road cars;
- for the bike.
Also, when choosing tires need to know the indices of speed and capacity. If the load index is between 76 to 83, it means that the load on each wheel should be from 400 to 487 kg, respectively. This index is suitable, for example, Lada. Indexes speed is often denoted by the letters L and Y, where L - the speed of 120 km / h, and Y - no more than 300 km / h. Naturally, the fans of fast trains should choose the second option, since the tire with an index of L is not suited to high speed.
By way of sealing tires are divided into the chamber and tubeless. In the chamber tire fits a camera that is designed to hold a compressed air. Tires marked with the camera so: «TT», «TUBE TYRE» or «MIT SCHLAUCH». In the tubeless tire is no camera, and the air is retained in the Tires due to the pressure sealing side tape, and thanks to the rubber hermetic layer, which is superimposed on the inner cavity of the tire. Precisely because of this design, tubeless tires are valued more than the Tires with a camera. In the case of a puncture or damage tubeless tire does not deflate the ball, and the loss of air would be insignificant. And this, again, a pledge of safety on the road. So choose tubeless tires (marking - «TL» or «Tubless»).
According to the location cords distinguish between radial and diagonal tires. When choosing tires is important point. Of braided cords is tire carcass. If these threads in the frame overlap and are directed from bead to bead along the diagonal, this bias tire. These tires are cheaper than the radial, high-strength and are easy to repair. They are well soften the blow when driving on bumpy roads. One minus - tread wear out quickly.
If the ply cords in the carcass did not overlap and are arranged as meridians, the radial tire in front of you. These tires are better than the diagonal of the following parameters:
- have a large carrying capacity (17-20%)
- firmly adhere to the road surface;
- less heat, and weigh less;
- tread less deformed;
- suited for relatively high rotational speed.
If you pay attention to the tires, so-called indicator of deterioration of the tread. On the tread pattern is a special projection. When the tread wears out much, an indicator that shows clearly speaking. If on a summer tire tread depth is 2 mm, then it should be changed, the same thing for winter tires, if the depth reached 4 mm.
If you are going to travel by car during rainy weather or very humid areas, it is best to choose a special rain tires. Their advantage over conventional in the fact that there are special tread grooves and channels, which seemed to divert water to the sides. Due to this tire is tightly pressed to the road and risk of loss of control decreases. But the weather is dry these tires do not naturally fit. Marking rain tires - «AQUA CONTACT» or «AQUATRED».
If we talk about the cost of the tire, then buy more expensive tires, you will not lose anything. In the manufacture of expensive tires use the new technology last cord of design, quality materials and a special rubber compound. Remember: saving money on tires, you save money on their own security. Approach to the choice of tires with full responsibility, and they will last you a long time!
