Types of Tyre Wear Patterns and Causes
As they cover miles and miles of tarmac, gravel and dirt, the tyres on our vehicles will become worn and will eventually need to be replaced. However, there is no uniform way for our tyres to wear down – tyre wear takes on many patterns, and certain patterns can be symptoms of further problems, so it is important to be able to spot it in order to avoid exacerbating the issue.
Here are the main types of tyre wear that we will be covering:
- Camber wear
- Feathered wear
- Cupped wear
- Centre wear
- Shoulder wear
Select a type of tyre wear:
CAMBER WEAR (ONE-SIDED WEAR)
What does camber wear look like?
If one of the shoulders of your tyres has worn down considerably while the other has changed very little, this is camber wear. It’s characterised by a gradual slope from one side to the other, and is much easier to identify than other types of tyre wear which, in turn, means that you get to the root of the problem quicker and get it sorted!
What are the causes of camber wear?
Considerable wear on the inside and outside edges of the tyre can be caused variously by suspension misalignment, a bent strut, a dislocated strut tower, a broken or weak spring, or collapsed or damaged control arm bushings.
If you notice that your tyres are starting to exhibit camber wear, then it’s best to call a local tyre expert, such as Tyres Northampton, as soon as possible, as any of the above issues can indicate that there’s a far more serious underlying issue at play.
FEATHERED DIRECTIONAL WEAR
What does feathered directional wear look like?
Feathered wear isn’t exactly easy to identify by simply looking at the tyre, since the wear itself is made up of small rivets and dips that follow a particular direction on the tyre’s surface. Because of this, in order to identify this type of wear, you will have to start by running your hand along the tyre: if it feels smooth one way but rough the other way, then feathered directional wear is occurring.
What are the causes of feathered directional wear?
Feathered directional wear could be caused by a variety of different mechanical problems associated with your vehicle. However, these are arguably the most common: toe misalignment, worn tie rod ends, bent steering linkage and arms or worn idler arms.
If any of your tyres are showing signs of feathered directional wear, then we would recommend you get them looked at by a professional as soon as possible. Issues like bent steering linkage could mean that your vehicle isn’t actually safe to drive, so it’s best to confront these issues as soon as possible so you can get safely back on the road.
CUPPED WEAR (CUPPING WEAR)
What does cupped wear look like?
Cupped wear is signified by cups and dips appearing around the edge of the tread. Unlike the other types of tyre wear, cupped wear doesn’t follow a specific pattern, which makes the wear itself look much less uniform than, say, camber wear. So, if you notice dips and cups appearing sporadically over the surface of your tyres, you’ll know that this is cupped wear.
What are the causes of cupped wear?
If you think that your tyres are showing signs of cupped wear, then the problem is likely to do with your tyres/wheels, rather than something mechanical. For example, it could mean that one of your tyres is out of balance, or your shock absorbers and struts have weakened.
If you have noticed that your tyres are exhibiting cupped wear patterns, don’t wait around, give Tyres Northampton a call today and ask about our wheel alignment services.
What does centre tyre wear look like?
Like feathered wear, it’s not always easy to spot when your tyres are showing signs of centre wear, given that the centre of your tyres tend to be out of sight underneath the wheel arches. However, if you do peek under and take a look, you will notice a strip around the centre your tyres where the tread has worn down.
What are the causes of centre wear?
If the centre of your tyre is more worn than the shoulders, then it means that the worn tyres could be overinflated, causing a bulge in the middle. With this in mind, it’s always worth being cautious if you inflate your tyres yourself at a petrol station, and over the following few weeks, make sure to check your tyres for centre wear.
It’s also worth noting that overinflating your tyres can cause permanent damage to the sidewall, something which will cause them to degenerate much quicker. On top of this, overinflating your tyres before a long summer’s drive could lead to a blowout due to further tyre expansion, so be very careful before adding extra pressure.
What does shoulder wear look like?
Unlike centre wear, shoulder wear should be pretty easy to spot because, of course, the shoulders will be more worn than the centre. While the shoulders and edges of tyres will always round off (although perhaps to different extents), tyres with more severe shoulder wear will look almost tube-shaped by comparison.
What are the causes of shoulder wear?
The main cause of shoulder wear is underinflation. If a tyre becomes underinflated, the shoulders are likely to sag slightly, meaning that the edges of the tyre are actually touching the road when they normally shouldn’t. Ultimately, this means that the shoulders get worn down much quicker than the centre.
General Tyre Wear CausesSome of the problems that can cause irregular tyre wear include:
- Suspension issues
- Incorrect wheel alignment
- An internal fault with the tyre/tyres
- Driving on under/overinflated tyres
