Condition of tires, rims state

After checking tightly screw the lid valve special key (Fig. 1.240). When the pressure is above or below the specified values decreased security deteriorating driving performance, comfort and fuel consumption, as well as increased tire wear. Excessively low blood pressure can lead to heat tires, internal injuries and due to this at high speeds to the running surface of the peeling tires and even to their rupture. Hidden damage to the tires can not be eliminated subsequent adjustment of air pressure.

Curbs moving at low speed and if possible a right angle. Hit a sharp curbs can lead to hidden damage to tires and rims, which manifest themselves later in the form of leaks, which lead to the fall of the set pressure (Fig. 1.241); Regularly check the tires for damage (punctures, cuts, cracks and dents on the sides). Verify that no damage to the wheels. If any damage or excessive wear should apply to service stations.

NOTICE Damage can lead to rupture of the tire.

Height tread

wheels

Regularly check the height of the tread pattern. If the wear in the front than the rear, swap the rear and front wheels. Wheels with the best protector should be installed in front (Fig. 1.242). Adjust tire pressure. To ensure safety, tires should be replaced at a height of 2-3 mm Tread (winter tires - 4 mm).

Minimum permissible height of the tread pattern (1.6 mm) is achieved when the tread wears out before the wear indicator (TWI). Several signs of wear are shown at the same distance from each other in the pits running surface. Their situation was also pointers to the side of the tire (Figure 1.243).

General recommendations on tire

At low altitude tread greatly increases the risk of aquaplaning. Tires get old, even if the car does not drive or drives low. Unused spare wheel after 6 months to apply only in extreme cases and only at a slow ride. Never place used tires, whose origin is unknown. In order not to impair brake cooling, use only shields the wheels, admitted for this car.

Winter tires

Winter tires at a temperature below 7 ° C provide improved safety, so they should be installed on all wheels. Summer tires in its construction have limited features for winter operation. If the maximum allowable speed for winter tires less than the car, attach the index plate with a permissible maximum speed of winter tires in a conspicuous place of the driver.

NOTICE When using the spare wheel with summer tires may change driving characteristics. Urgent replace the damaged tire, otbalansiruyte wheel and set it on the car.

Wheel Caps

In the case of application is not approved by Opel caps wheels and tires need to pay attention to the fact that the tires had no protective thickening.
