I will share my experience with you on this page as I end up using more tires during my first two months of getting my first Matrix 2008 model car.

It’s so annoying that I ended up buying new tires when I never had the plan to do so. But that could result from my ignorance on how to maintain the tires and things I should do and those I should not.

To start with, what are the causes of cracks in tires?

How to fix cracked tires

Whenever you see cracks in a tire, it is an indication that the polymer in the rubber is already breaking apart. But what are the things that could make the polymer break apart?

  • Chemicals can cause cracks

It is a good thing to take care of your tire by washing it regularly. However, you might be damaging your tire to maintain it using some chemicals that could hasten the breakdown of the polymers in the rubber.

You need to be very careful and selective with the product you choose for washing or cleaning your tire. Ensure it cannot cause damages. I was faulty because I can’t count the number of detergent products I’ve used to wash my tire.

So once I notice it’s one of the causes of cracks, I had to stick to one particular product that I know could be of less harm to my tire.

  • Improper use

If you don’t have the care of your tire in mind whenever you drive, you are likely to get new tires frequently. Improper use of tires can accelerate the breakdown process of the polymer.

You need to pay attention to how you handle the tire. Mind you, if some of the other parts of the car have an issue, you might still manage to move it, but once your tire gets damaged, moving the car becomes an issue.

If the tire is not an off-road tire, never should you take it off-road. It is not polite to take the tire over snow or icy surface area if it is summer. Those are means of improper use for you to understand.

  • Improper air inflation

Frequent low pressure can cause cracks on a tire. The fault could be on you as you fail to know the psi of your tire. You need to know your tire air pressure limit, and never should you exceed or fall below it.

Some cars like mine will indicate the dashboard that I have an issue with my tire pressure, and then I have to fix it. However, not all cars can do the same. You need to constantly check using a pressure gauge before you drive your car in such a situation.

Making a conscious effort to check will help to ensure you lower the chance of cracks in your tire due to lack of adequate air pressure.

  • Exposure to extreme weather conditions

Lots of sidewall cracks on the tire can be caused by exposure to too much heat or cold. Excessive heat or sunlight can make the tire rubber get dry, leading to quick degradation of the polymer, which will lead to cracks.
