Wheels and tires. Rotation, replacement, balancing and leaving. Snow chains. "Sekretki" of wheels. Elimination of trembling of a wheel.

Rotation can be made for economy reasons not less often than through 5000 km, or at emergence of signs of non-uniform wear of protectors. However remember that in case of successful rotation of all four wheels you, eventually, should replace all tires at the same time.

Though in interests of preservation of optimum road performance to carry out rotation it is not recommended.
As carrying out this procedure demands a car raising over the earth and removals of wheels, check at the same time and operation of brake mechanisms (address to the Section Check of brake system).

Even if you are not going to make rotation, at least check reliability of an inhaling of bolts of fastening of wheels.


To carry out rotation follows according to the special scheme so that the direction of their rotation did not change.

Address to information in the Section “Poddomkrachivaniye and towage” Introductions for the correct raising of the car and wheel change.

The car should be lifted the winch or to establish it on support that all four wheels were lifted over the earth. Make sure that the car is reliably fixed!

After the completion of procedure of rotation check and adjust pressure in tires and do not forget to check reliability of an inhaling of bolts of fastening of wheels.

Replacement and balancing of wheels

At replacement of wheels it is recommended to keep the direction of their rotation as change of the direction brings in raised to wear of tires. It is not recommended to rearrange also forward wheels back and on the contrary.
At an inhaling of bolts of fastening of wheels it is necessary to apply a dinamometrichesky key surely. It guarantees a uniform inhaling of all bolts.

At replacement and dismantle of tubeless tires for reasons of safety it is necessary to replace the rubber gate surely.


 PERFORMANCE ORDER

1. Weaken bolts of fastening of a wheel on the car standing on the earth. For this purpose tighten the parking brake or include the first transfer so that the car was not rolled away.

2. Remove a screw-driver a cap from locking bolts of fastening of a wheel. Insert against the stop a key into the lock. Thus shlitsa costs in parallel to an oval groove. Turn a key on 90 ° and remove with a cover. Installation is carried out in return sequence. At a key vynimaniye the plug should nestle on a bolt of fastening of a wheel. Put on a cap. a/b - a bolt of fastening of a wheel, is zinced/is chromeplated, with - a locking bolt, chromeplated. Address to an accompanying illustration.

3. If there is a protection of bolts of fastening of a wheel, the wheel acts in film as follows: a cover (1) slightly turn to the left a key and remove. Then insert an adapter (3) into a bolt (2) and unscrew it. Address to an accompanying illustration.

Surely carry with itself in a tool set an adapter (3).

4. Lift and establish the car on supports.

5. Turn a wheel so that the gate (the bottom arrow on an accompanying illustration) was below.

6. Before removal of a wheel mark with a felt-tip pen the provision of a disk concerning a nave that the otbalansirovanny wheel occupied the former situation. Address to an accompanying illustration.

Depending on type of a disk various bolts of fastening are applied. It is necessary to apply only the bolts allowed by BMW firm.

7. At installation not original disks from light metals it is necessary to apply bolts of fastening also corresponding to them instead of the original. It is recommended for a spare wheel of BMW applied earlier, to have with itself the corresponding bolts of fastening
8. Disks from light metals have a covering a colourless varnish for protection against corrosion. At replacement of a wheel watch to damaging a covering. At damage correct defect a varnish.
9. Before installation of a wheel clear aligning corbel on a nave and an adjacent surface of a wheel of dirt and the remains of greasing and slightly grease aligning corbel with bearing greasing.

10. Clear fastening bolts of dirt. At damage or corrosion bolts replace. The carving of bolts should not be oiled or plastic greasing. Address to an accompanying illustration.

11. Before wheel installation into place insert into the top carving opening an assembly opravka. Such opravka is available in a set of the onboard tool. After installation of several bolts an opravka remove.

12. Tighten bolts of fastening of a wheel cross-wise in stages. The inhaling moment for all bolts makes 100 Nanometers. Address to an accompanying illustration.

The unilateral inhaling of bolts of fastening or their inhaling with the various moment a wheel and/or a nave can be drawn. At installation of new wheels through 1000 km of run bolts of fastening are necessary for tightening the established moment of an inhaling.


If the car is equipped with navigation system, after replacement of a wheel or the tire it is necessary to make system calibration.

Balancing of wheels

Serial wheels pass balancing at manufacturer. Balancing is necessary for elimination of non-uniform distribution of masses and discrepancies of manufacturing of details.

At car movement neotbalansirovanny wheels lead to jolting. At high speed the steering wheel starts to shiver.

As a rule, trembling is shown in a certain range of speeds and disappears at reduction and increase in speed.

The similar phenomena lead over time to damages of hinges of a suspension bracket, the steering mechanism and shock-absorbers.

Wheels it is necessary to balance each 20 000 km of run and after each repair which lead to redistribution of masses on wheels.

Recommendations on the care of tires

Tires have "memory". It means that maloperation with them, in particular, frequent arrival on a border of the road or moving through rails, leads after a while to their damage.

Cleaning of tires

It is not recommended to clear the tire a vapor jet. If the nozzle of the device is too close to the tire, it leads to destruction of a rubber layer within several seconds even if cold water is applied. The tire which has passed such cleaning, should be replaced for the purpose of safety of operation of the car.

The tire, long time being in contact to oil or greasing is subject to replacement also. Thus the tire in these places вспучивается, then accepts a usual form and outwardly does not look damaged. However after that loading ability of the tire decreases.

Storage of tires

To store tires it is necessary in a dark, dry and cool place. Contact of tires to oil or greasing is not recommended.

Wheels should be stored in horizontal situation or be suspended for disks in garage or a cellar.

Before removal we prick it is necessary to lift in them pressure of air (on 0.3 - 0.5 bar).

It is necessary to establish winter tires on the disks.

Running in of tires

Tires have very smooth external surface. Therefore new tires should be rolled (it treats and a spare wheel). After a running in the surface of the tire becomes rough.

The first 300 km it is necessary to move with new tires especially carefully on wet roads.

Snow chains

To establish snow chains it is possible only on driving wheels (on a back axis). At application of wheels in the size of 17 inches installation of snow chains is impossible.

At installation of snow chains speed of movement of the car should not exceed 50 km/h. On roads, on having a snow and ice covering, snow chains are necessary for removing.

It is necessary to apply only the chains allowed by BMW firm.

Additional sekretok installation of wheels

 PERFORMANCE ORDER

1. Weaken bolts of fastening of a wheel.
2. Lift and establish the car on supports so that the wheel freely rotated.
3. Unscrew bolts of fastening of a wheel so that the wheel freely moved on a nave.
4. Turn a wheel so that the gate was below
5. Turn the top bolt of fastening of a wheel and insert instead of it a zamkovy bolt (the top arrow).
6. Turn out a bolt of fastening of a wheel and insert instead of it a zamkovy bolt (the top arrow).
7. In this situation (a zamkovy bolt above / the gate below) wrap a cross / crosswise by hand fastening bolts.
8. Tighten fastening bolts cross-wise the moment of 100 Nanometers.


Such way of installation of a zamkovy bolt minimizes an imbalance arising owing to installation of heavier zamkovy bolt.

Elimination of trembling of a wheel of the car

Trembling of a steering wheel at achievement by the car of a certain speed, as a rule, is a consequence of disbalance of wheels.

Check

 PERFORMANCE ORDER

1. Check pressure of air in tires. If necessary pump up them.
2. Make a control trip. As it is possible establish a cause of defect more precisely: achievement of a certain speed, quality of the road, the entrance and exit moment from turn.
3. Lift and establish the car on supports.
4. Check a centering of disks of wheels. Thus the nave or a brake drum should act over boards of disks of wheels or, at least, to be aflush. Otherwise the disk is subject to replacement.
5. Check a suspension bracket. For this purpose it is necessary to check rezinometallichesky support, hinges, shock-absorbers and disks.
6. Remove wheels and clear them. If it is necessary, remove from a tire profile small stones.
7. Check depth of a profile of tires and compare among themselves. At the wrong wear of tires in front and/or behind it is necessary to check installation of wheels and to adjust. Thus deviations of a convergence should not leave for the top limit of the admission.

For measurement of geometry of wheels the special equipment which is available only on HUNDRED is required.

8. Make a trial trip and check, whether malfunctions are eliminated.

Check of radial and axial palpation of wheels

 PERFORMANCE ORDER

1. Lift the car and establish it on supports. Bring a measuring tip of the indicator to external, and then to a lateral surface of the tire. Slowly turn a wheel a hand and take readings of the indicator. Chalk note a place of the maximum palpation.
2. If palpation exceeds the value established by Specifications, wheels it is necessary отбалансировать in stationary conditions. Thus wheels by the balancing car should be отцентрованы the same as on the car Centering of wheels on the central opening in a conic clutch is not carried out. The admissible imbalance in both planes makes 5 g.

Elimination of radial palpation

 PERFORMANCE ORDER

1. Lower air in the tire and press a tire edge into a disk bed.
2. Turn the tire on 120 ° on a disk.
3. Pump up the tire and again check radial palpation.
4. If the maximum value is exceeded, turn the tire on a disk on 120 ° and check radial palpation.
5. If palpation does not exceed admissible value, отбалансируйте a wheel.

Check of radial and axial palpation of disks

 PERFORMANCE ORDER CHECK REMOVAL INSTALLATION

1. Establish a disk without the tire by the balancing car or on the car. Establish the indicator.

 

2. Check radial H and axial S disk palpation. On the extreme internal planes radial palpation, on the lateral internal planes - axial palpation is checked. Thus the local deviation of the indicator owing to roughnesses is not considered.

3. If values exceed specified in Specifications, the disk is subject to replacement.

 

Installation of wheels on the car

 PERFORMANCE ORDER

1. On the car lifted on supports establish wheels so that the place with the maximum radial palpation was above. In this situation tighten bolts of fastening of a wheel a dinamometrichesky key the moment given in Specifications.

If the difference in wear of separate tires is insignificant, wheels with small radial palpation and the maximum imbalance establish on a forward axis.

2. Make a trial trip. If still forward part of the car has fluctuations and the steering wheel shivers, the reason is the residual imbalance which it is necessary to eliminate with a way of additional balancing.

Balancing of wheels on the car

 PERFORMANCE ORDER

1. At carrying out balancing of driving wheels surely establish both tires of one axis on rollers.
2. The drive of wheels should be carried out from the car engine that wheels rotated synchronously.
3. Make a trial trip.

If malfunctions completely are not eliminated, it indicates existence of radial palpation or a production defect of one or several tires. HUNDRED they are not defined by means. To eliminate them it is possible only replacement of lobbies and/or back tires. Tires should be replaced only parno on one axis.
