The causes of premature wear on the tires can be clearly read in the observation of the appearance of irregular tread wear.

Generally a bad tire alignment can be the cause of the wear of the tires, likewise, the mechanical factors can influence the premature wear of the tires. Shock absorbers, springs, ball joints, connecting rod terminals etc., can be some of the components that are in poor condition and that due to their poor performance end up damaging the tires.

The tires must be adjusted so that they point directly forward and are parallel to each other and perpendicular to the road.

If a tire does not rotate parallel to the direction of travel but at an inclined angle, the tire wears on one side which causes unilateral wear, or on only one side of the tread.

Additionally, we must bear in mind that manufacturers regulate the convergence / divergence of tires to optimize the handling of the vehicle, this can lead to unilateral wear impossible to avoid without compromising the stability of the vehicle.

Unilateral wear
The most frequent cause of unilateral wear is geometry adjustments deviated from the specifications required by the vehicle.


The deviations in the geometry of the tires are produced in a progressive way due to irregularities of the terrain, such as stepping on bumps at high speed or climbing quickly on the sidewalks.

The modification of the suspensions to lower the height of a vehicle with low-profile tires has a decisive influence on the alignment of the wheels; changing parts of the address increases the tendency to misaligned the elements.

These changes not recommended by the manufacturers can affect the geometry of the axes, since although they are within the tolerance values ​​in static, it will not be so in dynamic and therefore will generate unwanted wear.

Central wear

This wear appears on the drive wheels of high displacement vehicles. Modern diesel vehicles have engines with a large torque that generate great wear due to friction (skidding) of the tires.

The large torque of these engines in dense traffic conditions as in the cities, accelerating and braking continuously sharpens the central wear of the tire.

Diagonal wear


The diagonal wear in an area is always around 45º of the direction of travel. Although it can occur in several areas of the tire, in general it only occurs in a certain one. Affected vehicles are usually front-wheel drive.

Diagonal wear almost always occurs on axles without traction, especially in the left rear position. Some vehicles are particularly susceptible to generate diagonal wear, while others are not at all. Diagonal wear occurs because the left wheel always rotates in an inclined plane (the road) even in a straight line.

The consequence is that diagonal forces appear in the area of ​​contact with the road and therefore areas with greater tendency to wear. The minimum tolerance values ​​respected by the manufacturer guarantee a reduction in the occurrence of this phenomenon.

Flat areas for brake blockage

Flattened areas as a result of a brake blockage cause a loss of rubber in the area of ​​the blockage. There is no component that can avoid great wear due to extreme braking conditions.

Inflation and rotation
Incorrectly inflated tires also cause wear. You can tell if the tires inflated too much by looking at wear patterns. Since if the center of the tire wears faster than the edges, the tire was exposed to excessive inflation, in the same way, if the edges wear out faster than the center band, the tire is deflated.

The tires must be rotated in strict compliance with the manufacturer's instructions (during the alignment and balancing process). The lack of rotation causes irregular wear that feels uneven to the touch and engraves a pattern on the tread.

Shock absorbers

Shock absorbers can cause the tires to wear unevenly, resulting visually in a "cup" shaped appearance.

Shock absorbers are designed to cushion excessive rebound when the vehicle travels on the road. A failed shock absorber does not stop the rebound, which causes a concentric pattern of uneven wear.

Wheel balancing

Problems with tires such as deformation at the rim can cause uneven tire wear patterns, small weights attached to the wheels when the tires are unbalanced can fall; likewise, an imbalance can be the cause of the wear of the vehicle suspension system.

Other problems
The joints, springs, control arms dropped, damaged or worn, all this contributes to tire wear. These worn components cause wear of the tires that appear on the inner or outer edge of the tire and deteriorate more quickly than the rest of the tire.

Therefore, before replacing a tire, it will be necessary to check the components of the suspension systems as this will depend on the lifetime of the tires.

Finally, keeping a tire in good condition helps to maintain the safety of the occupants of the vehicle, since having tires in good conditions can have better control of the vehicle in case of an emergency situation.
