Check of a condition and pressure in tyres

It is very important to support tyres in a good condition and with correct pressure — tyre breakage at any speed is very dangerous. Deterioration of tyres is influenced by driving type — sharp braking and acceleration, or fast movement on turn will accelerate deterioration of tyres. As a rule, forward tyres wear out faster, than back. The exchange of tyres (lobbies on back, "rotation" of tyres) will lead to more uniform deterioration. However, if it is required, it is possible to replace all four tyres at once! Remove nails or the stones which have got to a protector. If after extraction nailing the tyre has started to pass water, insert a nail so that to note a puncture. Then immediately replace a wheel, and repair the punctured tyre.
Regularly check tyres that there was no damage to the form of cuts or выпучивания, especially in lateral walls. Periodically remove wheels, clean an internal part and external surfaces from a dirt. Investigate internal lateral surfaces of a rim of a wheel on signs ржавления, corrosion or other damages. Easy wheels with cast disks are easily damaged at arrival on a border; steel wheels also can be bent. Installation of a new wheel — a very often unique way of elimination of serious damage.
New tyres should be отбалансированы in the established position, but can repeatedly be demanded to balance them in process of deterioration. Unbalanced tyres will faster wear out, as well as steering and suspension bracket details. Disbalance of wheels is usually expressed by vibration, especially on some speed (usually about 80 km/hour). If this vibration is felt only through a steering possibly it is necessary what to balance only forward wheels. However if vibration is felt on all car, back wheels are probably unbalanced also. Balancing of wheels is necessary for carrying out at servicing deport.

Depth of drawing of a protector — the visual control

CHECK

1. New tyres have markers of deterioration of a protector () which will appear when depth of drawing of a protector will reach approximately 1.6 mm. Positions of markers are designated by a triangular label on a lateral wall of the tyre () (address to an accompanying illustration).

Depth of drawing of a protector — the manual control

CHECK

1. Deterioration of a protector can be supervised the simple inexpensive device known as a measuring instrument of depth of drawing of a protector (address to an accompanying illustration).

The pressure control in the tyre

CHECK

1. Regularly check pressure in cold tyres. Do not regulate pressure in tyres. Do not regulate pressure in tyres right after car operation (address to an accompanying illustration).

DETERIORATION OF THE PROTECTOR

Lateral deterioration

Insufficient pressure
(Wears out from both parties)
Insufficient pressure causes a tyre overheat as the cord and a protector is too bent will not sit correctly on a road surface. It will cause loss of coupling with a road covering and excessive deterioration, not to mention danger of sudden breakage of the tyre because of rise in temperature.
Check up and adjust pressure

Wrong disorder of wheels
(Wears out on one party)
Repair or replace suspension bracket parts
Difficult movement on turn
Reduce speed!

The central deterioration

Перекачивание
Перекачивание causes fast deterioration of the central part of a protector of the tyre, and also coupling with a road covering decreases and danger of rupture of the tyre increases.
Check up and adjust pressure
If sometimes it is required to pump up tyres of your car more a high pressure specified for maximum permissible loading or supported high speed, do not forget after to reduce pressure to normal value.

Non-uniform deterioration

Forward tyres can wear out non-uniformly as a result несоосности wheels. On the majority of servicing deports it is possible to check up and adjust installation of wheels for moderate loading.

Wrong disorder or longitudinal inclination of an axis of turn of wheels
Repair or replace suspension bracket parts.

Faulty suspension bracket
Repair or replace suspension bracket parts.

Unbalanced wheels
Balance tyres.

Wrong installation of a convergence
Adjust installation of forward wheels.
