Why Do Michelin Tires Dry Rot? Causes And Prevention

I know how bad it feels when your tires prematurely show symptoms of dry rotting, leaving you with a hefty bill to replace them. Understanding the causes and prevention can save you from blowouts and keep you and your passengers safe.

Why do Michelin tires dry rot? There can be various factors, including improper storage, exposure to sunlight, high temperatures, and low tire pressure, can cause dry rot in Michelin tires. These factors can contribute to the deterioration of the rubber, leading to cracks and brittleness. 

What Is Tire Dry Rot?

Tire dry rot is a condition that is visible when the rubber composition of a tire begins to degrade over time. It is also known as sidewall cracking or weather checking. 

Dry rotting reduces the grip of the tire and makes it hard. Harder tires provide decreased control, especially in winter. These hard tires fail to provide traction, making them highly hazardous.

Checking only the surface of a tire is not sufficient. It is important to remove the tire from the wheel axle and thoroughly inspect it inside and out, as dry rot can also occur inside the tire.

When the tires start to rot, they show small cracks that usually go unnoticed and later damage the whole tire part by part. 

Severe dry rot on vehicles can be a safety hazard. As the rubber deteriorates, it can cause a slow leak in the tire resulting in the expansion of the rubber. It leads to a higher risk of blowouts or other failures. 

What Causes Michelin Tires To Dry Rot? 

These are the primary reasons why Michelin tires dry rot. 

Causes Of Michelin Tires Dry Rot

Aging 

Aging is one of the major causes of tire dry rot. The natural aging process of the tires loosens the rubber compound leading to reduced elasticity. This makes the tire prone to cracks and dry rots. 

UV Rays

Direct exposure to sunlight can affect the tire’s rubber, as it is susceptible to ultraviolet light. It compromises the structural integrity of your tires, and they can crack and dry out due to losing flexibility over time. 

Lack Of Use 

Tires that sit for a long time get prone to dry rot due to the degradation of rubber compounds over time. The heat generated by the friction between the road and the tire help keeps the tire supple and flexible. This is one of the major reasons why Michelin tires dry rot. 

Underinflation

Underinflated tires don’t just affect the tires, but they can also have adverse effects on the vehicle. Tires that are improperly inflated experience more stress on the sidewalls and excessive flexing, which can cause the rubber to weaken and break down, leading to dry rot
