Tire Dry Rot

What is Tire Dry Rot?


Tire dry rot, also known as sidewall cracking, is a condition that affects the rubber of your tires, causing it to degrade over time. It can lead to visible cracks, reduced flexibility, compromised safety, and a much shorter lifespan for your tires

As a BMW owner near Norwood, Westwood, or Dedham, MA, understanding tire dry rot is crucial for maintaining optimal vehicle performance and safety.

Luckily, the team here at BMW of Norwood is here to help.

Tire Dry Rot Explained


Tire dry rot occurs when the rubber compounds in tires break down due to exposure to environmental factors such as sunlight, ozone, and temperature fluctuations. This degradation weakens the tire's structural integrity, leading to cracks on the sidewall and tread areas. Over time, dry rot causes tires to become brittle and lose their elasticity, increasing the risk of blowouts and other failures while driving.

When left untreated, tire dry rot can cause lasting damage to your tires and much more frequent tire service or tire replacements

What Causes Tire Dry Rot?

Several factors contribute to the development of dry rot in tires. Knowing some of the causes can help you prevent it during your everyday commute.

Some of the most common causes of tire dry rot include:

  • UV Exposure: Prolonged exposure to sunlight is one of the primary causes of dry rot. UV rays break down the rubber's chemical bonds, causing it to crack and fade.
  • Weather Conditions: Extreme heat and cold can accelerate dry rot, making it essential to protect tires from harsh environmental conditions.
  • Lack of Use: If a vehicle is rarely driven or stored for long periods, its tires are more susceptible to dry rot. Regular use helps keep the rubber flexible.
  • Under or Over-Inflation: Incorrect tire pressure can also stress the rubber, leading to quicker deterioration.

Tire dry rot affects the condition and functionality of tires, so it’s crucial to have them serviced as soon as you notice this state of decay.

How Do I Know My Tires Have Dry Rot?

As important as it is to know the causes of tire dry rot, it’s even more essential to know some of the signs that your tires may have it. 

To determine if your tires have dry rot, look for the following signs:

  • Cracks on the sidewall or tread
  • Tire discoloration
  • Brittle texture
  • Low air pressure

If you notice any of these signs or begin to believe your tires are starting to decay, you should schedule service for them as soon as possible.
