"Gazelle" Gas-2705>> Running gear>> Wheels and tyres>> Maintenance service
While in service the car it is necessary to make a timely tightening of nuts of fastening of wheels to avoid разбивания fixing apertures, to delete a rust from wheels and to make them подкраску.
For maintenance of the greatest service life of tyres it is necessary to be guided by following rules:
- To support in tyres demanded pressure. Pressure is checked on cold tyres before departure. At stops in a way it is necessary to examine tyres and visually to supervise in them pressure of air. Not to go at the lowered pressure in tyres even on small distances. Not to reduce pressure in the heated up tyres, letting out from them air as during movement the pressure increase is inevitable owing to heating in them of air;
- To make balancing of wheels. At tyre factory in gathering with wheels are balanced dynamically with the help грузиков, established with both parties on закраинах rims. Check and balancing of wheels with tyres should be made through 12 000-20 000 km of run at the special stand. The admissible residual disbalance from each party of a wheel with the tyre should not exceed 40 г on a wheel rim. In case it is not obviously possible to make dynamic balancing of wheels, it is possible to execute the static. Thus balancing грузики it is necessary to establish on закраине the rims, located more close to a surface of fastening of a disk of a wheel;
- At returning in park and at stops it is necessary to examine tyres and to delete from them nails, a wire and other subjects. To put the car follows on a pure and dry place. Do not suppose hit on tyres of oil, gasoline, an oil paint;
- At parking of the car more than 10 days it is necessary to put it on supports to unload tyres. Do not suppose car parking on the lowered tyres;

Fig. 6.14. The scheme of shift of tyres




- Shift of tyres (6.14) should be made fig. if necessary. As the basis for shift of tyres necessity of reception of uniform deterioration of all tyres, including spare, and also maintenance of correct selection of tyres on axes can serve. On an axis it is necessary to establish the tyres having identical deterioration of a protector, and more reliable tyres should be established on a forward axis of the car.
Limiting degree of deterioration of a protector of a tyre cover corresponds to residual depth of flutes of 1,6 mm that is defined by gauging or on deterioration indicators. The deterioration indicators, which height of 1,6 mm, in the form of continuous strips of rubber are located in belts of a protector and noted on боковинах tyre covers by badges TW1.
