Signs of Tire Dry Rot


Tire dry rot can wreak havoc on your vehicle’s functionality. That’s why it’s a good idea to do regular visual inspections of every tire on your vehicle. Tire dry rot can happen on any kind of vehicle including four-wheeled cars, motorcycles, trailers, and more.

When you’re inspecting each of your tires, there’s two specific things you need to look for that are indicative of tire dry rot. The first sign of tire dry rot is deep and/or spidering cracks on the inner or outer walls of your tires. Another sign you’ll usually see is discoloration of the tire around these cracks.

What this cracking means is that the tire’s materials are breaking down before your eyes. This breakdown makes the tires weak and unsafe to drive on, especially in its later stages when you begin to see extreme discoloration around the cracks.

What Causes Tire Dry Rot

There are many different causes of tire dry rot. Some of the most common causes of tire dry rot are as follows:

  • General wear and tear from regular use
  • Consistent driving without enough pressure in your tires
  • Exposure to the sun and excessive heat
  • Exposure to other extreme environmental elements, like snow and cold

One thing that causes all of these issues is time. Sooner or later, it’s likely that every tire will get dry rot because the materials that make up the tire naturally breakdown after five or six years regardless of its use or care.

Preventing Tire Dry Rot

Certified service

While tire dry rot happens over time, there are ways that you can delay it and even prevent it. If you use your car often, you need to always make sure each of your tires has the right amount of air in them as recommended by the manufacturer in your owner’s manual.

You should also make a habit of storing your vehicle, or the tires if you take them off at any point, in a climate-controlled area. This will protect your tires from extreme heat and cold as well as the snow and ice.

If you plan to store your vehicle for any long period of time, you should store it with a board under each individual tire. While in storage, you should still be checking the air pressure of each time once and month and adjusting it to keep it at the right pressure.
