What Causes Cracks?

Do you want to know why your tires are cracking? Several factors can contribute to this.

Read and consider the following causes of cracks:

What Causes Cracks

1. Exposure to Water

The tires will be elastic if they are exposed to water for a prolonged time. When they are elastic, it will lead to degradation where cracks can be produced in the tires.

2. Not Using the Tires for a Long Time

The tires should be used to avoid cracks. When not in use, antioxidants and other chemicals in the tires are not properly distributed.

Thus, cracks can be created because of long-term disuse.

3. Exposure to Chemicals or Oils

If the tires will be exposed to oil, gasoline, and other chemicals, they can have cracks. Even some cleaning agents have a high level of acidity that can cause the tire to rot.

4. Improper Tire Pressure

Cracks can be formed between treads if you will have improper tire pressure. Numerous forums reveal that overinflation can be a cause of tire cracks.

This is more likely to happen when your tire is old. As the rubber stretches through overinflation, it can crack.

In the same case, underinflated tires that will hit bumps can stretch the rubber and can produce cracks.

5. Manufacturing Defects

This may not always be the case, but it happens sometimes. This is more common if the quality of your tires is not very good.

Low-quality materials are more prone to cracking. So, if this happens to you, you must refer to the craftsmanship warranty of your tires.

Know if they can have a replacement for your tires because of manufacturing defects.

6. Extreme Cold

The non-winter tires that are used in winter can have cracks. This is because the tires cannot withstand cold temperatures which can result in irreversible cracking.

7. UV Light

Your tires have some chemicals in them. When exposed to direct sunlight, these chemicals can break down.

Thus, the tire can crack. This will be likely to happen because it is hard to keep your tires away from sunlight.

You are always out on the road and the sunlight can reach your tire. The only thing that you can do is to choose the spot where you can park your car.

8. Natural Aging

When your tire reaches 5-6 years old, you cannot do anything, it will start to crack. Cracks will begin to build up in the sidewall and the tread area.

This thing is typical because the rubber compound will begin to deteriorate.

9. Using Your Tires All Year Long

One of the reasons that cause cracks is that you are using your tires all year long. Maybe you have summer tires that you have used for the whole year.

When this happens, the tires cannot withstand other seasons. Due to the differing temperatures, the tires will crack.

10. Heat and Humidity

Hot temperatures can make your tire expand. The contraction can be a cause of cracking.

So, you have to store your tires in an ideal environment where the temperature does not change so much.

11. Low-Quality Tire Shine

You must be careful in using tire shine products. Some are aggressive and can dry out your tires.
