When driving for a long time at speeds up to 140 km/h (if the current traffic regulations allow such a speed), the tire pressure should be maintained at the recommended pressure for the given tire type and size. If the vehicle is regularly driven at speeds above 140 km/h, the vehicle should be fitted with tires of the appropriate speed category, which can be purchased from tire manufacturer dealers.
The air pressure in a hot tire can increase by 41 kPa compared to a cold tire.
Exceeding the recommended air pressure in tires leads to the following consequences:
- Deterioration of ride smoothness and comfort.
- Damage to the tire frame.
- Rapid wear of the tread in the central part of the tread.
Insufficient air pressure in tires leads to the following consequences:
- Tires squeal when cornering.
- Increased steering effort.
Rapid and uneven wear of the tread along the edges of the tread.
- Damage to the wheel rim and tyre casing.
- Cord thread rupture.
- Overheating of tires.
- Deterioration of vehicle controllability.
- Deterioration in fuel economy.
Uneven air pressure in tires mounted on the same axle can cause the following:
- The vehicle's tendency to pull away when braking due to differences in braking forces.
- Deterioration of controllability.
- Car pulls away during acceleration.
- Constant moment on the steering wheel when the car is moving in a straight line.
Note: The use of fast-penetrating compounds is not always effective when the wheel is difficult to remove. However, if such agents have to be used, care must be taken to ensure that they are applied in small quantities and only directly in the vicinity of the central hole of the wheel. If fast-penetrating compounds get into the contact surfaces between the wheel and the hub or brake drum, this may lead to the wheel mounting bolts becoming loose while the vehicle is in motion.
