Ever wonder why your car malfunctions for no apparent reason? You may have just gotten your vehicle back from your sibling. Did they do something which led to the malfunctioning of your car? Maybe they took it out to the sand dunes of the UAE and did not know the correct way to drive, or perhaps you just need to stop over-thinking and stop the blame game.
We will explore one crucial mechanical cause and then the most common human error.
Deterioration of the technical condition of shock absorbers and violation of the geometry of the rear axle
With a decrease in the shock absorbers’ shock absorption capacity, the wear of the tire tread also increases, especially on roads with significant unevenness. During operation, the vehicle’s rear axle may be deformed or displaced relative to the front axle. Deformation of the axle beam leads to the rolling of the wheels with some discrepancy. This causes sawtooth tread wear that eventually spreads to the entire treadmill. Depending on the axle’s deformation, the tires wear on one or both sides of the vehicle. When the rear axle is skewed, one-sided sawtooth wear of the tire tread occurs on both sides of the car, and it is noted in the first thousand kilometers. If the reasons for this phenomenon are not eliminated, then in the future, wave-like wear of the pattern will appear on the tread over its entire surface.
There are cases when, after repairing a car that had an accident, repeated adjustments of the camber and toe-in angles of the front wheels to average values did not eliminate the tire treads uneven wear. This can only be explained by the fact that the geometry of the body’s power elements was disturbed in the car as a result of the accident. Whether this is so, you can check at a service station. The fact is that so-called control points are applied to each car’s bottom per the design documentation. By the location of these points with the help of special devices, it is possible to determine their deviation from their initial position, which means that a conclusion can be drawn about the deformation of the body’s power elements. In this case, after repairing the body, the increased wear of the tire tread is eliminated.
Inept car driving
The performance and service life of tires also largely depend on driving techniques on the driver’s skill and experience. Here it is necessary to take into account:
- starting off with wheel slip;
- harsh braking, especially with wheel slip;
- driving at high speed on turns and sharp overtaking;
- collisions with various road obstacles;
- pressing against curbs when approaching sidewalks, crossing rail tracks at high speed, etc.
With a sharp start, the load on the vehicle’s transmission units increases, the intensity of local wear of the tire tread as a result of wheel slip increases significantly.
With sharp braking, the projections of the tread elements slide along the road surface, the friction and heating in the contact area of the tread with the road increase, and the tread rubber’s wear increases. The higher the driving speed at which hard braking is performed, and the harder the braking is completed, the faster the tread wears out. With frequent skidding (skid) braking, the tread’s local wear first appears, and then the breaker and carcass layers are destroyed. When an overloaded vehicle is braked sharply, the tread may come off.
Before you even think of blaming your tires, car tires in Dubai are of top-notch quality regardless of the brand – of course, some brands are proven to be of the best quality, but that doesn’t mean you MUST buy them. Always make sure your tires are compatible with the vehicles make and model.
If the car makes a sharp turn at high speed and the centrifugal forces due to its rotation, the centrifugal forces that occur when the vehicle turns are also acting on the wheel. The combined action of these forces increases the road’s corresponding reaction force, which tends to pull the tire beads away from the rim.
