3.18. A wheel puncture

The wheel puncture is trouble which each driver sooner or later faces. Air can leave a punctured wheel quickly or slowly, it depends and on size of a subject which has pierced a wheel, and from what tyres are established on the car: chamber or бескамерные. With a small nail in бескамерной to the tyre it is possible to go many days before you will notice that «the wheel has lowered».

It is very important to define in time that there was a wheel puncture. During movement pay attention to behaviour of the car: if it began to be dispersed badly, the effort to a steering wheel has increased at maneuvering or course stability has worsened, necessarily check up pressure in wheels.

The most simple way to repair a wheel – to address in the nearest шиномонтажную a workshop where repair will make quickly, professionally and, as a rule, under quite reasonable price.

THE PREVENTION Do not try to reach to шиномонтажной a workshop on completely lowered wheel: it is enough to pass so some tens metres and the tyre should be thrown out.

It is necessary to replace the damaged wheel spare. This simple enough operation demands, nevertheless, some skills.

At a wheel puncture include the alarm system, smoothly brake the car till the speed of 2-3 km/h and on the first transfer try to move cautiously to edge проезжей parts and to stop as it is possible more to the right at a roadside and if it is possible – outside of проезжей parts. If road conditions allow and it does not contradict requirements of Rules of traffic, at a puncture of any wheel on the right side of the car nestle on the right roadside, at a puncture at the left – to left. Avoid to stop the car in places where it is expensive badly it is looked through – in abrupt turns, on descents and liftings, bridges, tunnels. If the car remained on проезжей parts, first of all provide own safety and safety of other participants of traffic! Include the alarm system and establish a sign on an emergency stop.

It be required to you: a key for nuts of fastening of wheels («баллонный» a key), a jack, a basic rack, противооткатные an emphasis, a spare wheel, a manometre, the pump.

THE PREVENTION Before the work beginning establish the car on an equal platform and enclose противооткатные an emphasis under wheels. If you change a forward wheel, brake the car a lay brake.

1. A ballonnym key ослабьте an inhaling of five nuts of fastening of a wheel.

GOOD ADVICE That it was easier to turn away wheel nuts, it is possible to take advantage not of hands, and a foot, coming from above on the handle баллонного a key. For simplification of this operation it is recommended to get special баллонный a key with the telescopic handle.

2. Prepare for installation a spare wheel for what remove a decorative cap on a spare wheel, having hooked its handle баллонного a key...	3.... Turn away three nuts of fastening of a spare wheel to an arm, remove a spare wheel and put it on the earth near to a replaced wheel.

4. Will hang out a replaced wheel, having raised the car a jack, and, …

GOOD ADVICE The jack put to the car has unsuccessful enough design and to use it inconveniently. Therefore we recommend to get a hydraulic jack (most conveniently to use the small jack shown in a photo подкатного type).

5.... Definitively having turned away a nut, remove a wheel.

PREVENTIONS Raise the car a jack only on the size necessary for removal and installation of a wheel. Try, that the car was in the hung out condition with the removed wheel as less as possible time. If work on a soft ground, enclose under the jack basis a thick board. Do not apply to this purpose bricks – they easily break up also the car can break from a jack, hard having injured you.

6. Establish a spare wheel. Wrap fastening nuts, without tightening them it is definitive.

7. Lower the car and in regular intervals tighten bolts of its fastening. Tighten wheel nuts cross-wise. In order to avoid damage of a disk of a wheel do not try to "hold on" a nut of fastening of a wheel, pressing a foot the key handle.

GOOD ADVICE To feel necessary effort of an inhaling of nuts of fastening of a wheel, at first apply динамометрический a key (the inhaling moment see in enc. 1). Do not grease a fastening hairpin is can lead самоотворачиванию nuts on the move.

8. Check up pressure in tyres and if necessary finish it to norm.

GOOD ADVICE If you replaced a wheel on the journey, do not forget to clean in the car the removed wheel and the tool. On cars the Shevrole-field establish бескамерные tyres. If you do not possess sufficient skills of installation of tyres, we advise to you not to try to make this work independently. One damage боковины – also it is necessary to buy a new tyre cover or to insert the chamber. In a desperate situation it is possible to take advantage of the special first-aid set for repair бескамерных tyres without разбортовки or hermetic for tyres. To apply them it is necessary according to the applied instruction. Than бескамерная the tyre is better chamber? First, бескамерная at a puncture lowers very slowly, it is possible, pumping up, weeks to go with a nail in a wheel, there will be no yet a possibility it to repair. Secondly, when at very considerable run from бескамерной tyres will start to act delays металлокорда, it still can be used as a spare wheel. The chamber into such tyre cover to insert it is useless – it will be pierced already at the first inflating.
