On the car establish only radial tyres.
In radial tyres of a thread of a cord are located on the least way between tyre boards. The brekernyj belt surrounds a thin and elastic skeleton of the tyre and provides its stability.
In бескамерных tyres the chamber is replaced with the vulcanized inside layer with high air impermeability. The board of such tyre should be established on a disk rim reliably and tightly. Absence of the chamber in the tyre reduces weight of a wheel and simplifies its installation on a disk rim.
Marks of tyres are put on it боковине. The width of the tyre, its design and diameter of a rim of a disk make the minimum information necessary for marks of the tyre
In flutes of drawing of a protector of tyres there are «indicators of deterioration of tyres» in height 1,6 mm the movements of the tyre located at right angle to a direction. These indicators in quantity from six to eight (depending on firm of the manufacturer) are placed through equal distances on a tyre circle. Markers on боковине tyres (for example, letters «TWI» or the pictogramme in the form of a triangle) show a site of indicators of deterioration of tyres.
Tyres can be maintained before achievement of depth of a profile of 1,6 mm, that is profile flutes should have depth on all surface of the tyre not less than 1,6 mm.
Optimum performance data of tyres are reached only in case of installation on all wheels of the car of tyres of one design.
At installation of the tyre do not establish them on the damaged, deformed rim of a disk with corrosion traces.
At installation of the tyre with the directed road drawing (are defined on an arrow on боковине tyres) it is necessary for it to provide a correct direction of rotation. The optimum behaviour of the tyre concerning coupling with a road covering and deterioration will be thus provided.
Maintenance of recommended pressure of air in tyres is especially important at movement on high speeds. Therefore necessarily check pressure of air in tyres, at least, once a month and before each distant trip.
Pressure of air always check at cold tyres.
At air elevated pressure in нагретых tyres do not let the air out at all from the tyre.
At considerable change of loading it is necessary to change accordingly pressure of air in tyres.
Lowered or air elevated pressure in tyres reduces term of their service and worsens road performance of the car.
Constant check of a condition of tyres will allow to find out in due time intensive deterioration and to eliminate its reason that will allow to avoid more serious consequences.
On the all-wheel drive car, except that, all tyres should be identical model of the same manufacturer. Otherwise interaxal differential because of an arising difference in frequency of rotation of wheels of both axes it will be wrong to redistribute the twisting moment of the engine having on a back axis that can negatively affect controllability of the car.
While in service the car under the influence of the various reasons balancing of wheels can be broken that is shown in occurrence of vibration of a steering wheel.
The disbalance of wheels conducts to the raised deterioration of details of a steering, tyres and car suspension brackets, therefore at disbalance occurrence necessarily отбалансируйте wheels anew.
