The foundation of cars depends upon tyres. But the tyres tend to wear out after a specific time. Moreover, tread wear impacts the tyre’s health, performance and road grip capability. The worn-out tyres compromise safe driving and require more power from the engine to move the vehicle. Different factors and conditions cause various tyre tread wear types and affect the car’s performance.
Speaking of the tread wear types, here is a detailed overview of the different tread wear and the reasons behind it.
What is Tyre Wear?
Incorrect wheel alignment, underinflated tyres, and suspension problems cause tyre wear and tear- affecting the fuel efficiency, car’s performance and road grip. One can measure the tyre’s tread depth using the coin method, and if they find it less than 1.5 mm, manufacturers recommend changing the tyres.
The tyre treads are crucial indicators of the tyre’s health. Moreover, different tyre tread wear results in tyres not gripping on the road. Let’s go through the types of tyre wear and their causes, signs and symptoms.
DIFFERENT TYPES OF TYRE WEAR AND THEIR CAUSES
With the availability of different types of car tyres and tread types, each wears out differently depending on the driving habits and conditions. The following tyre tread wear types happen due to various factors:
Centre Wear
As the name suggests, when the centre part of the tyres wears out, it is a disadvantage of the overinflated tyres. Since tyres bulge from overinflation, it hits the middle part of the tyres when on the road.
One can identify this tyre tread wear type from the thin treads in the centre line of tyres. Avoid overinflation, and always inflate the tyres according to the manufacturers’ recommendations.
Edge Wear
Contrary to the centre tyre wear type, edge wear means the thin tread lines on the side of the tyres. It happens due to the underinflated tyres. However, the edge wear may indicate worn-out steering arms or wheel alignment issues if the tyres have required air pressure.
Inflate the tyres as recommended by the manufacturer and get the wheels aligned to avoid edge wear, also known as side tyre wear.
Cupping Wear
Worn-out shock absorbers and suspension system failure, the cupping patches appear on the tyre. This tyre tread wear type appears in the same line and looks like a scoop worn-out from the tyres.
It is the most critical tread wear, and one needs to get the suspension repaired and replaced to avoid cupping wear.
Patchy Wear
When the tyres don’t make complete contact with the road, it results in patchy wear or flat spots. This type of tyre tread wear occurs due to imbalanced tyres. To avoid this patchy tyre wear, ensure that when performing wheel alignment, get the tyre balancing as well.
Additionally, check the tyre balancing when equipping the car with new ones because the patchy wear gets worse over time.
Toe Wear
When performing wheel alignment, a zero toe angle means a perfect alignment. However, toe-in or toe-out angles cause the outside or inside edge to wear out. Moreover, toe wear, also known as one-side wear, can happen because of bad ball joints or faulty springs.
Camber Wear
The vertical angle of the wheels means camber. That said, camber wear means wearing out on the inside or outside part. Camber wear distinguishes from toe wear because it affects the edges: whereas, camber impacts the exterior and interior of the tyres.
Sidewall Wear
It happens mainly due to the parking beside the curbs. This type of tread wear is common in urban areas. Identifying this type of tyre wear sooner to avoid tyre buckle, or it can also make the tyre’s core weaker.
A weaker core will lead to tyres losing pressure frequently and may result in other problems, such as lower fuel efficiency, reduced road grip and handling problems.
Feathering
Aggressive driving at higher speeds or understeering and oversteering are the significant causes of feathering. This tyre tread wear type means worn-out tyres on one side and sharp on the other.
That said, it is hard to identify feathering visually. However, one can check feathering by moving the hand on the tread.
That wraps the overview of tyre tread wear types. Since different types of tyre tread patterns meet specific functioning factors, worn-out tyre treads affect performance. The more early you identify the common tyre problems, the better your chances of improving the fuel economy, vehicle performance and tyres’ health.
Therefore, when you buy a used car in the UAE, check all the common car problems to drive safely and comfortably.
