Feathering is a type of uneven tyre wear that leaves tread blocks smooth on one edge and rough on the other. This guide explains what causes feathering, how to recognise it early, and what you can do to prevent it through proper alignment, suspension checks, and tyre maintenance.
There are plenty of different issues that can plague drivers, especially when it comes to tyre maintenance and inspections.
Uneven tyre wear is one of the most challenging issues to overcome, not only because it hints at an underlying issue with tyre alignment and positioning, but because it is difficult to reverse.
Feathering is just one example of uneven tyre wear – with this article dedicated to helping drivers understand what a feathered tyre is and why it’s so problematic.
What is a Feathered Tyre?
When you look at the outer tread of a tyre, you will notice a pattern constructed from a series of rubber blocks. These sit on the edge of the tyre and are responsible for making contact with the road, facilitating good grip and traction as well as a smooth and comfortable drive.
Feathering occurs when the tread blocks start to wear down on one side, while remaining sharp on the other. When inspecting a tyre for feathering, you will notice that when running a hand in one direction the tyre edge feels smooth, while the other direction feels rough.
Why is Feathering a Problem?
You might think that, provided the tyre has tread blocks, it doesn’t matter where the wear has occurred or what impact it has had on the shape of the blocks.
However, feathering indicates some level of inconsistency with the alignment of the tyre.
To understand this, we need to look at what should happen as a tyre becomes worn.
As a tyre is used, the tread blocks wear down – growing smaller and less prominent. It’s important that this wear and tear is measured to check it doesn’t fall below the minimum legal tread limit – and to check that any wear that does occur is evenly balanced.
Feathering means that the tyre has started to wear down as above, but that the pressure is concentrated on a specific side of the tyre. This creates the uneven wear which can ultimately impact comfort, safety, and performance.
What Causes Feathering?
With all that in mind then, what causes feathering across car tyres and how do drivers minimise the risk of feathered tyres?
The most common causes of feathering include:
- Worn or damaged suspension
- Misaligned tyres / wheels
- Poor quality or cheaper tyres which are not strong enough to withstand different terrains, surfaces, and driving conditions
- Driver habits such as sharp cornering
Any or all of these issues can impact the way a tyre becomes worn through driving, with the best way to minimise issues being regular checks across both suspension and alignment.
