On the car establish only radial tires.
In radial tires of a thread of a cord are located on the smallest way between tire boards. The Brekerny belt surrounds a thin and elastic framework of the tire and provides its stability.
In tubeless tires the chamber is replaced with the vulcanized inside layer with high air impermeability. The board of such tire should be established on a rim of a disk reliably and tightly. Lack of the chamber in the tire reduces mass of a wheel and simplifies its installation on a disk rim.
Marking of tires is put on it боковине. The width of the tire, its design and diameter of a rim of a disk make the minimum information necessary for marking of the tire
In flutes of drawing of a protector of tires there are «indicators of wear of tires» in height of 1,6 mm the movements of the tire located at right angle to the direction. These indicators in quantity from six to eight (depending on firm of the manufacturer) are placed through equal distances on a tire circle. Markers on боковине tires (for example, the letters "TWI" or the pictogram in the form of a triangle) show a site of indicators of wear of tires.
Tires can be maintained before achievement of depth of a profile of 1,6 mm, that is flutes of a profile should have depth on all surface of the tire not less than 1,6 mm.
Optimum performance data of tires are reached only in case of installation on all wheels of the car of tires of one design.
At installation of the tire do not establish them on the damaged, deformed rim of a disk with corrosion traces.
At tire installation with the directed road drawing (are determined by an arrow on боковине tires) it is necessary for it to provide the correct direction of rotation. The optimum behavior of the tire concerning coupling with a paving and wear will be thus provided.
Maintenance of recommended pressure of air in tires is especially important at movement on high speeds. Therefore surely check pressure of air in tires, at least, once a month and before each distant trip.
Pressure of air always check at cold tires.
At an air elevated pressure in warm tires do not let the air out at all from the tire.
At considerable change of loading it is necessary to change respectively pressure of air in tires.
Lowered or the air elevated pressure in tires reduces term of their service and worsens road performance of the car.
Continuous check of a condition of tires will allow to find in due time intensive wear and to eliminate its reason that will allow to avoid more serious consequences.
On the all-wheel drive car, besides, all tires should be identical model of the same manufacturer. Otherwise the interaxal differential because of an arising difference in frequency of rotation of wheels of both axes will incorrectly redistribute the torque of the engine falling on a back axis that can negatively affect controllability of the car.
In use the car under the influence of the various reasons balancing of wheels can be broken that is shown in emergence of vibration of a steering wheel.
The imbalance of wheels conducts to the increased wear of details of a steering, tires and car suspension brackets, therefore at emergence of an imbalance surely отбалансируйте wheels anew.
