Dry Rot Tyres: Everything You Need to Know About It

Tyres are one of the most important parts of your vehicle as they keep it mobile. Despite this, they often go unnoticed until a problem arises. One such issue that demands immediate attention is tyre dry rot. It develops due to environmental factors, poor maintenance, and infrequent use.

Even tyres from top brands like Michelin and Goodyear can develop dry rot if not properly cared for. It silently weakens them and makes them unsafe for driving. The worst part is that most car owners don’t even know about this issue. Therefore, it often goes unnoticed until it leads to major issues.

In this post, we will tell you everything about dry rot, including its causes, prevention tips, and how to deal with it.

What is Tyre Dry Rot?

It is a condition where the rubber compound deteriorates and causes visible cracks and brittleness, especially on the sidewalls. It often happens due to age, exposure to sunlight, and improper storage.

Though premium tyres from reputable brands like Bridgestone are designed with high-quality compounds to resist such damage, they are not completely immune. Over time, the rubber loses its flexibility and becomes more prone to dry rot.

Causes of Dry Rot

The following are some primary reasons behind this issue.

Prolonged UV Exposure

Excessive exposure to ultraviolet (UV) rays breaks down the rubber compounds and leads to cracks and brittleness. Even tyres with high durability can get damaged without proper UV protection. Using covers and parking in shaded areas can help avoid this issue.

Low Tyre Usage

When you don’t drive your car for some time, it can lead to dry rot. Without consistent flexing, rubber loses its elasticity, leading to cracking. High-performance tyres deteriorate faster without movement, as they need frequent rotation to maintain their structural integrity.

Exposure to Harsh Chemicals

Frequent contact with cleaning agents and road salts degrades the rubber. They strip protective oils from tyres, causing premature drying. If you leave this issue unnoticed, it can lead to dry rot.

Improper Storage Conditions

Storing tyres in hot, humid, or poorly ventilated areas speeds up the decoration. Excess heat accelerates the loss of essential oils within the rubber, while poor ventilation promotes cracking.

Age

Tyres age over time, even when you don’t use them due to the natural oxidation of rubber compounds. They typically last 6–10 years, based on the brand and conditions. Pirelli and Falken tyres are highly durable. However, they cannot resist aging and become more prone to dry rot over time.

Tips to Prevent Tyre Dry Rot

The following are some effective tips and strategies to prevent dry rot.

Protect Tyres from UV rays

Using UV-protectant sprays or covers can shield tyres from harmful radiation. If possible, park your vehicle in a garage or shaded area. This practice is essential to preserve the longevity of tyres and reduce the risk of dry rot.

Drive Regularly

Regular tyre movement is necessary to maintain their elasticity. When driven, the flexing motion distributes protective oils evenly across the surface. Therefore, you should drive your vehicle regularly to mitigate the risk of this issue.

Maintain Proper Inflation

Incorrect tyre pressure accelerates wear and promotes cracking. You should check the pressure monthly and adjust it to the manufacturer’s recommendations. It will extend the life of the tyres.

Avoid Hard Washing Agents

You can choose rubber-safe cleaners and rinse thoroughly during maintenance. This precaution helps prevent chemical-induced dry rot. It ensures tyres retain their flexibility and durability.

Store Properly

Store tyres in a cool, dry environment away from direct sunlight and ozone-emitting appliances like heaters. Try to elevate them during storage to prevent pressure spots. This is especially important for unused spare ones.

How to Deal With Dry Rot?

If you notice the sign of dry rot, you can deal with it by taking the right step. All you need to do is listed below.

Inspect the Damage

First of all, you need to examine tyres for visible signs of dry rot, such as cracks on the sidewalls, discoloration, or a brittle texture. Minor cracks may be manageable, but extensive damage compromises their structural integrity. Regular checks help identify issues before they worsen.

Reduce Stress

If the damage is minor, limit unnecessary driving and avoid heavy loads or high speeds. It will reduce stress on affected tyres. This precaution can temporarily extend their usability. However, this is not a long-term solution.

Replace Severely Affected tyres.

If dry rot has significantly affected tyres, replacement is the best solution. You should opt for tyres from reputable brands such as Hankook, BFGoodrich, and Continental. They offer high durability and are resistant to environmental damage.

Seek Professional Advice

You should visit specialists to evaluate the severity of the dry rot. Professionals can recommend whether repairs are possible or if immediate replacement is necessary.

Now, you can identify dry rot early and adopt preventive measures to avoid extensive damage. If it has already affected the tyres, immediately opt for a replacement to ensure optimal performance and safety of your vehicle.
