Chassis faults, tire defects (Opel Vectra C)

Extraneous noises

1. Normal road noise - cannot be corrected.

2. Tire noise - check the condition of the treads and tire inflation pressure.

3. Wheel bearings are worn or damaged, or their tightening force has weakened.

Vibrations

1. Check the condition of the wheel bearings by alternately jacking up the corresponding corner of the car and rotating the wheel manually. Listen to the sounds coming from the bearing. Remove the bearings and check their condition.

Severe tire wear on both sides of the working surface

1. Tire pressure is too low.

There is excessive wear on the outer edge of the treads

1. The tires are not inflated correctly.

2. Turns are made too sharply.

3. The front wheel alignment angles are out of adjustment (excessive convergence).

4. The suspension arm is bent or twisted.

There is excessive wear on the inner edge of the treads

1. The tires are not inflated correctly.



2. The front wheel alignment angles are out of adjustment (convergence).

3. Steering components are damaged or loose.

Severe wear of the tire in the middle of the working surface along the entire circumference of the tread

1. Tire pressure is too high.

Uneven tread wear

1. Static and dynamic imbalance of the wheel, possibly due to excessive lateral runout of the disc, too much play in the bearing joints.

There is excessive wear on the treads (not in one particular area)

1. The tires are not inflated correctly.

2. Wheel balance is disturbed.

3. The wheel rims are damaged.

4. Excessive wear of suspension or steering components.

There is localized wear of the tread

1. Wheel balance is disturbed.

2. The discs are damaged or bent.

3. There is a defect in the tires.

Uneven wear in the middle of the tread

1. Static wheel imbalance, possibly due to excessive vertical runout.

Severe wear of individual areas in the middle of the tread working surface

1. The result of sudden braking.

Saw-tooth tread wear, often accompanied by an invisible tear in the tire's fabric base

1. Vehicle overload. Check the condition of the inner walls of the tires.

Rubber tongues on the side edges of the tread (scaly wear)

1. Wheel alignment is incorrect.

2. The tires are worn out.

3. Shock absorbers/strut assemblies are faulty.

Formation of burrs on one side of the front wheel tread

1. Wheel alignment is out of adjustment.

2. The tires are worn out.

3. Frequent movement on wavy surfaces. Fast movement on turns.

Cord breaks. At first only visible from the inside

1. Driving over sharp rocks, tire impacts, etc. at high speed.

One-sided wear of the working surface of the tread

1. Check the camber adjustment.

2. There is a fault with the ABS, check the condition and reliability of the clamp connection of the ground of the return pump (in the hydromodulator).
