Do Michelin Tires Dry Rot? Causes and Prevention - A Comprehensive Guide

Do Michelin Tires Dry Rot?

When it comes to car maintenance, one of the most overlooked but crucial aspects is tire care. Michelin tires are known for their high quality and durability, but like any tire, they are susceptible to dry rot. Dry rot occurs when tires degrade over time due to exposure to environmental elements and lack of proper maintenance.
In this article, we will delve into the causes of dry rot in Michelin tires and offer valuable prevention tips to extend the life of your tires. Whether you are a car enthusiast, a daily commuter, or want to ensure your safety on the road, understanding and preventing dry rot is essential.

Do Michelin Tires Dry Rot Causes and Prevention

What is Dry Rot?

Dry rot, also known as sidewall cracking, is the deterioration of tire compounds over time, resulting in visible cracks on the tire’s sidewall. These cracks weaken the tire’s structural integrity, making it more prone to blowouts and accidents.

Exposure to UV Rays

Prolonged exposure to sunlight and UV rays can accelerate the breakdown of tire compounds, leading to dry rot. Parking your vehicle outdoors for extended periods without protection can hasten the process.

Age of the Tires

Even if your Michelin tires have sufficient tread depth, they can still be affected by dry rot if they are old. Tires lasting over six years are more susceptible to dry rot, regardless of the remaining tread life.

Low Tire Pressure

Underinflated tires create excessive flexing of the sidewalls, leading to heat buildup and dry rot. Regularly check and maintain the recommended tire pressure to avoid this problem.

Lack of Use

Vehicles that are not driven regularly are prone to dry rot. Tires require regular motion to maintain their flexibility and prevent the onset of dry rot. If you have a spare set of tires or a classic car you don’t drive frequently, consider rotating the tires periodically.

Climate and Weather Conditions

Extreme weather conditions, such as hot summers or cold winters, can accelerate tire degradation. If you live in an area with harsh weather, take extra precautions to prevent dry rot.

Prevention Tips for Dry Rot

Prevention Tips for Dry Rot

Now that we have explored the causes, let’s focus on prevention strategies to keep your Michelin tires in excellent condition:

Regular Inspection

Perform visual inspections of your tires regularly. Look for any signs of cracking, bulging, or damage. Catching early signs of dry rot can help you take preventive action before the issue worsens.

Store Tires Properly

If you have spare or seasonal tires, store them in a cool, dry, and dark place away from direct sunlight and extreme temperatures.

Check your tire pressure at least once a month and before long trips. Properly inflated tires prevent dry rot and improve fuel efficiency and handling.

Drive Your Vehicle Regularly

Avoid prolonged parking and regularly drive your vehicle to maintain tire flexibility if possible.

Use Tire Covers

When parking your vehicle for extended periods, consider using tire covers to protect the tires from UV rays and other environmental elements.

Rotate Tires

Regularly rotate your tires to ensure even wear and tear, reducing the risk of dry rot on specific spots.


Dry rot in Michelin tires is a common issue that can compromise your safety on the road. By understanding the causes and implementing preventive measures, you can extend the life of your tires and ensure a smoother driving experience. Regular inspections, proper storage, and maintenance are crucial to avoiding dry rot and maximizing the performance of your Michelin tires.

Remember, your tires are the only point of contact between your vehicle and the road. Prioritize their care, and they will reward you with enhanced safety and longevity.
