4.2.1. Repair of wheels and tires

Manufacturer all models are equipped with the steel radial tire (the tubeless radial tire). Together with tubeless tires can be used only "safe" ободы, so-called deep ободы with the hampy. Hamp is a ring-shaped ledge on the landing shelf of a rim which holds a tire board from moving on a rim bottom. At asymmetrical deep rims the tire should be mounted over the narrow landing shelf of a rim, i.e. from outer side of a wheel.
At installation of tires with a strelovidny profile, it is necessary to observe the established direction of rotation. To pay attention to marks in the tires having a certain assembly situation: to watch designation external / inside on a lateral wall of a tire.
The centering of disk wheels on a nave of a wheel of a forward axis is an installation on the central opening or on wheel screws. For protection against deep corrosion at each installation it is necessary to put on aligning nest on a nave of a wheel of a little plastic greasing for bearings.
The torque of screws of a wheel makes 110 N · m.

Before installation of the "dry" screw conic surfaces are greased with plastic greasing for kacheniye bearings.

Use of protective disks or brake dustproof disks for a disk brake of Adam Opel AG is forbidden for the safety reasons. At installation of these disks it is impossible to achieve reliable fastening of a wheel. Transfer of a disk imbalance on a wheel negatively affects dynamic qualities. There is a danger of an overheat of brake system. If on the car similar disks nevertheless are established, it is necessary to know about existing risk.
This the recommended pressure of air in tires for summer and winter tires are on inside of the refueling hatch or on an average left rack of a body (an average right rack of a body in cars with a right-hand steering), and also in the operation manual. At change of the size of tires on inside of the refueling hatch the corresponding label with information on pressure of air in tires should be pasted, labels are available at service stations of service.
Use of a chain of antisliding is allowed only on driving wheels (a forward axis). Thus it is necessary to consider, it is possible what to use only small chains which on inside and on a protector of a tire do not act more than on 15 mm (including the chain lock).
At replacement of tires it is necessary to watch that the sizes of tires allowed by the manufacturer of the car were established only. Also the rules established by the law of this country should be observed! They contain all obligatory characteristics and the sizes of the equipment, e.g. connections of a speedometer, an expander of a wheel niche, the size of a rim, etc.
Requirements of competent authority should regulate a combination of the size of tires and a speedometer corresponding to them (number of turns on 1 m of a way). The corresponding permission to operation divides tires into groups. It follows from this that on the car tires of the suitable size, i.e. one group defined by characteristics of a speedometer can be established only. Marking of speed (S, T or H) has no value what on them and winter it is tires or summer.
All sizes of tires specified in documents, being applied to the car, can be established also in winter updating (tires with high factor of coupling with tire darling for driving on dirty and snow-covered roads) if any exceptions it is not provided.
Prevention: If the maximum speed of the car is higher than the maximum speed of winter tires, admissible speed of tires for driving on dirty and snow-covered roads should be designated by a badge in sight of the driver. It is recommended to establish winter rubber on all 4 wheels.
Winter tires (for driving on dirty and snow-covered roads) have tires restriction of speed, admissible maximum speed is determined by marking of used tires.
If established ободы wheels are not provided for installation of winter tires, when using flat covering caps it is obligatory to watch that long valves of tires were inserted. Also grooves обдува these caps should provide cooling of brake system.
To compensate constructive conditional fluctuation of weight on tires of the car and on rims of the wheels, the established wheels should be отбалансированы. The imbalance conducts to violation of kontsentrichny rotation of a wheel and steering violation, the clip of bearings of a wheel, parts of a steering drive and tires as a result increases. At first, before installation of wheels on the car, balancing is carried out on the stationary balancing device. After installation on the car the residual imbalance which arises, as a rule, from unbalanced rotating parts of the car (a wheel nave, a brake drum or a brake disk) can be revealed. to compensate this residual imbalance, wheels can be отбалансированы the mobile balancing adaptation (the final balance weight or the device of exact balancing).
