Dry Rot Tyres and What to Do About Them (Full Guide)

Sadly, dry rot is a natural part of tyre aging. Tyres deteriorate as they get older at the end of their lifespan. But there are a number of reasons why that problem might occur.

What is the time frame for tyre dry rot?

There are various responses since it substantially relies on several variables. Additionally, problems with tyre blowouts and dry rot are related. However, you won't be popping tyres when dry rot is still in its early stages.

Let's examine this problem and how to avoid it before new tyres are required.

How Does tyre Dry Rot Affect tyres?

Perhaps something other than tyres comes to mind when you hear the term "dry rot." But is a tyre that has dry rotted entirely distinct from that?

Usually, dry rot develops in wood. It is wood degradation brought on by diverse fungal species. They destroy the components of the wood that give it its strength. However, organic growth does not cause tyre dry rot.

Why do tyres dry rot if they are not the same?

When the rubber compound dries out, tyres begin to dry rot. It manifests either as a result of the tyre's natural aging process or by being subjected to incorrect tyre maintenance. The tyres can still be salvaged if dry rot is found early. Yet it has the potential to quickly deteriorate.

It is pretty likely to result in the tyre's inability to maintain air pressure. It may result in tread separation, dry rot tyre blowouts, or air leakage.

What Do Tyres With Dry Rot Look Like?

There are several ways tyre dry rot may manifest. Though you can probably guess where this is going given that it is known as sidewall cracking. How can you determine if your tyres have dry rot?

Tyre dry rot manifests itself in the following ways, ranging from minor cases to sidewall cracking:

  • Sidewall weathering - The sidewall section is tougher, and when handled, the rubber will peel off the tyre sidewall and footprint.
  • Tyre Sidewall Cracking: Tyre sidewall cracks, whether slight or extensive, can impair how a vehicle handles.
  • Tyre Tread Cracking - Advanced dry rot causes dry rot by spreading sidewall weathering over the tread region. Tyre damage

Tyres are suffering from dry rot when the black hue on their faces turns gray.

What Leads to Dry Rot in tyres?

For a reason, tyres with dry rot are often referred to as weather-cracked tyres. Tyre rot may be caused by a variety of external reasons, while weather damage from direct sunlight is the most frequent.

What causes tyre dry rot? These are the reasons why a tyre cracks:

  • UV rays from the sun's beams
  • High and low temperatures that are extreme
  • Running tyres that are under-inflated have low pressure levels.
  • Improper storage, particularly next to ozone-producing electrical equipment
  • Tyres that are not being utilized (or stored)
  • Make sure to buy high-quality tyres to prevent premature dry rot in your tyres. This guarantees their lifetime, provided they are properly cared for.

How long can you drive on a tyre that has wires exposed?

Don’t! Replace the tyre right away. No amount of driving should be attempted with such models due to the highly hazardous wires that are visible on the tyres. Consider buying a new tyre as soon as you can.


 How long until tyres begin to dry rot?

Depending on the environment they are utilized in, tyre tread and sidewalls can dry rot. Tyres dry out more quickly in sunny, arid locations, and after around 5 years, tyre sets develop dry rot. Humid surroundings, on the other hand, are able to slow down the aging process, extending its service life.

What tyre Cracking Level Is Too Much?

When the fractures between tyre treads and on the sidewall are wide and deep, tyre dry rot can be hazardous. Such sidewall breaking on the tyre is a sign that it will deflate. When tyre rubber begins to break in this way, it needs to be replaced right away.

Are little tyre cracks typical?

Tyre cracks are a sign of worn tyres or insufficient maintenance, therefore they may be expected. They are nonetheless indicators of a bad tyre, whether they are brought on by wear or damage. Tyres with severe dry rot need to be replaced right once, although cracks that are barely noticeable don't pose a threat right away.

Are Tyres With Dry Rot Dangerous?

Yes, tyres with dry rot are hazardous. Sidewall and tread area cracks are actually caused by dry deterioration. These fissures may result in air leakage that result in flat tyres. However, a blown-out tyre is not uncommon if the cracks in dry rotting tyres suddenly open up.
