Rotation and replacement of wheels. Chains противоскольжения


The scheme of rotation of wheels

The tyre supposing movement only in specified arrow

1. Rotation can be spent at occurrence of signs of non-uniform deterioration of protectors. However remember that in case of successful rotation of all four wheels you eventually should replace all tyres simultaneously.

As carrying out of the given procedure demands a car raising over the earth and removals of wheels, check up at the same time and work of brake mechanisms.


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

2. At faster deterioration of forward tyres it is recommended to interchange the position of forward and back tyres. Thus, service life of all four tyres is equalised.
3. Address to the information in subsection of Poddomkrachivanie and towage for a correct raising of the car and wheel change.
4. The car should be lifted лебедкой or to establish it on support that all four wheels have been lifted over the earth. Make sure that the car is reliably fixed!
Remarks on security measures

Do not replace separately any tyre. It is necessary to replace tyres on one bridge completely. Tyres with большей depth of a protector are established on forward wheels. Forward and back wheels should have tyres of the identical size and type, and at all-wheel drive cars also one manufacturer and one execution of a protector. The tyres which have worked more of 6 years, it is necessary to apply only in case of failure, thus it is necessary to be careful at driving. At replacement and removal бескамерных tyres it is necessary to change the gate necessarily.
5. In case of application of tyres with a protector supposing movement only in a certain direction that is underlined an arrow on a lateral surface of the tyre, the specified direction is necessary for observing. Only thus achievement of necessary road qualities of the car, namely hydroplaning, stability on road, low noise level and low deterioration is provided. If the spare wheel owing to failure has to be established with a rotation opposite direction, such application should be only time, since. Achievement specified above road qualities of the car thus is impossible. It especially concerns movement on wet road. Therefore it is recommended to co-ordinate speed of movement with conditions of road and to reinstall the tyre according to the set direction of rotation.
Spare wheel
6. The spare wheel can be established both on a lobby, and on a back axis.
7. The spare wheel is intended only for short-term use and it is necessary to replace it with the usual as soon as possible.
8. After installation of a spare wheel pressure in its tyre should make 4.2 bar.
9. With the established spare wheel it is impossible to exceed speed of 80 km/hour. It is necessary to avoid the maximum acceleration of the car, intensive braking and sharp turns.
10. At installation of a spare wheel the road gleam under a corresponding axis decreases approximately for 30 mm.
11. It is not necessary to apply spare wheels from cars of other types.
12. It is not supposed to establish two or more spare wheels.
Replacement of wheels
13. Remove a decorative cap of a wheel. For this purpose use mount and wire скобу from a tooling. Wire скоба it is established on an aperture of a cap or on an edge. Pass mount through скобу and, having pulled mount from a wheel, remove a cap.
14. On the car standing on the earth, tighten a manual brake and ослабьте bolts of fastening of a wheel.
15. Lift the corresponding party of the car and fix on supports.
16. Turn away the top bolt of fastening of a wheel and on its place screw an adjusting pin. Use of an adjusting pin facilitates installation of a spare wheel.


Disks from easy alloys are protected from corrosion by a transparent varnish. Be careful not to damage a varnish covering. At covering damage, cover a disk with a varnish coat.

17. For an exception “прикипания” disks of wheels to a nave, before wheel installation, apply a thin film greasings on the fillet of a nave aligning a disk of a wheel.
18. The zinced wheel bolts can be applied only on capital stamped disks.
19. Disks from easy alloys fasten only the chromeplated wheel bolts on which there is a conic rotating washer. This washer established under a head of a bolt, protects a disk surface at a tightening of bolts.
20. Before ввинчиванием do not grease a carving of bolts of fastening of a wheel.
21. Standard bolts of fastening of wheels have the sizes М14 х 1.5 х 27.5. The size of a head on a turn-key basis 17 mm.
22. A tightening of bolts of fastening of a wheel make in regular intervals in some stages in diagonal sequence.
23. The moment of a tightening of bolts of fastening of a wheel of 120 Nanometers.
Chains противоскольжения
24. Chains should be established only on forward wheels, as well all-wheel drive car.
25. Chains противоскольжения can be established only on tyres dimension 195/65 R 15. Installation of chains противоскольжения on an emergency wheel for technical reasons is not supposed.
26. It is necessary to use only мелкоячеистые the chains acting no more than on 15 mm (including замковые links).
27. At installation of chains противоскольжения it is necessary to remove full-size caps of wheels and decorative rings of disks. For safety reasons wheel bolts should be protected special caps.
28. Before movement on free from snow it is necessary for way site to remove chains противоскольжения. They worsen road performance of the car, raise deterioration of tyres and quickly collapse.
