For the correct choice of tires is important to consider many factors, especially individual vehicle. And while every motorist eventually becomes a professional in the selection of tires, is still time to mention all the features of the classification of tires. Car tires are classified depending on the destination, method of sealing, the profile shape and design. There is also a classification for the season. Now, a little More details on classifications.
By purpose machine tires are divided on the tires for passenger cars, which are intended for use in all climates with temperatures ranging from minus 45 C to plus 55 C, and tires for trucks vehicles. Tires for passenger cars, in turn, are divided into tubeless tires and chamber: Chamber Bus (Tube Type) – a type of pneumatic tire, where with the help of sealing the chamber, creates an air cavity, and the tubeless (Tubeless) – is a pneumatic tire, where the air cavity is formed under the rim and tire. It has increased gazonepropuskaemost. Tubeless tires tend to have a radical design of the framework. Bus radical design is marked with the letter R, or P, if it is not, therefore, cross-ply tire. Now a little about the classification of the shape profile. One of the most popular types of tires are toroid tire or tires usual profile, are performed chamber music and tubeless. Their profile is similar to a circle.
The average operating mileage of toroid tire is 40 – 80 thousand km. Low profile and sverhnizkoprofilnye tires have a lower ratio of the height profile. Both types of these types of tires enhance stability and handling. Low-profile tires are designed and sverhnizkoprofilnye mainly for cars and buses. There are also wide-bus they were compared with the usual profile tires have low rolling resistance and increased load capacity, and allow reduce fuel consumption. Their disadvantage is that their operation should be used in one car and the tires usual profile. There is another type of tires – tires arch. They have a profile in the form of an arch variable curvature of the low-powerful boards. Arched tires are tubeless. These tires are used as seasonal means of increasing the permeability of cars. They are placed on a special rim, instead of the usual tires. Disadvantages are high cost and a more complicated installation. The average mileage of tires arch during the operation in mixed traffic conditions is 40-45 thousand km, and on roads with a paved 20 – 30 thousand km. Depending on the Season car tires are divided into: Summer – have a hard rubber compound, it provides stability and the normal wear in the summer. But even at low temperatures below zero, they lose elasticity. Winter tires – On the contrary, have a soft rubber and does not lose elasticity even in the bitter cold. Are studded and non-studded. And all season – it's all-season tires with tread, but not all of these tires are suitable in Russian climate. All of this classification is not yet complete, but every motorist knows how important the right choice of rubber for safe driving.
