Driving with cracks in your tires is highly risky. Even though some people might consider it okay but it is not good advice. Those cracks get worse without you knowing, and that can become a big problem later on.

It is worth noting that the size or depth of the cracks doesn’t matter as they still are dangerous. Here are some key points about why tire cracking is a big deal:

So, if any of the above cases happen to you, remember that:

Now, with that, we will look at two cracking charts below that most likely happen.

2 Common Reasons Behind Tire Cracks: Understanding Sidewall and Tire Treads Issue

To understand the reasons behind small cracks in tires, it’s essential first to examine the factors that contribute to these cracking. Below we will be considering two factors, first on the sidewalls and then on the tire treads.

1. Intensive Sidewalls Issues

Sidewall cracks can occur due to various causes, such as:

Improper tire maintenance and neglecting to keep tires properly inflated also plays a role in sidewall deterioration. Let’s explore these factors:

Misusing Seasonal Tires Year-Round

One common reason for tire cracks is the improper use of seasonal tires throughout the year. Rather than using them during their intended seasons.

Effects of Humidity, Heat, and UV Light

Fluctuating temperatures can cause tire contraction and expansion, especially in substandard environments. It results in premature cracking.

Impact of Tire Pressure

Proper tire inflation is vital to avoid tire cracks. Underinflated tires generate excess heat and undergo extreme expansion and contraction, leading to cracking. On the other hand, overinflated tires stretch the tire’s inner compounds, increasing the risk of:

Choosing Low-Quality Tire Shine

Using low-quality tire-shining products leads to tire cracks:

Aging Tires and the Importance of Replacement

Car tires have a limited lifespan, and as they age, they become more susceptible to cracking and other forms of deterioration. Even with proper maintenance, tires will eventually reach a point where they need replacement. It is crucial to pay attention to the sidewalls for developing cracks and have the cracked tires replaced promptly.

2. Cracks Occurring on the Tire Tread

Tread cracks in tires are not common, but they can be very risky. They appear on tires due to factors like:

These cracks start on the tire’s sides and can move to the tread, the part that touches the road. If left untreated, they could lead to reduced traction and ultimately accidents.

Understanding the 4 Hidden Symptoms for Cracked Tires

Within the appearance of weather-cracked tires are the signs of potential danger. These hidden symptoms can include fine lines and fissures on the tire surface, often concealed amidst the tire’s tread patterns.

By recognizing these signs, you can take timely action to address potential issues and prevent further damage. Let’s take an in-depth look:

1. Brittle Texture in Tire Rubber

One of the prominent signs of cracked tires is the development of brittleness in the tire rubber.

2. Tears Affecting Tires

Whether the dry rot is mild or severe, you’ll notice visible tears or cracks along the sidewall of the tire. These cracks may appear as small lines and can extend to cover larger areas near the hubcap. The severity of these visible tears may vary depending on the extent of dry rot and the tire’s age.

3. Treaded Cracks

Advanced sidewall cracks also affect the tire tread which can be noticed on particularly the outer edge. The presence of tread cracks makes it challenging to control the car properly.

4. Changes in Tire Color Appearance

Another indicator of tire cracks is a change in the tire’s color.

3 Handy Tips to Check Tire Expiration Date to Ensure Safety

Taking just a minute to inspect your tires can reveal crucial information about their age and condition. This will, however, ensure a safer driving experience. Below is a step-by-step guide to help you check your tires’ expiration date:

1. Have a Close Look at Your RV Tire

Examine your tires closely to look for signs of aging, such as visible cracks or dry rot. If your tires show these symptoms, it’s a clear indication that they might be old. Remember that even if your tires appear to be in good shape, any tire that is six years old or more should be replaced with a new set to maintain optimal safety.

2. Check the Tires’ Sidewall Especially

On the sidewall of your tire, you will find the letters “DOT.” This indicates that the tire manufacturer adheres to the safety standards. These are set by the U.S. Department of Transportation (DOT) and the National Highway Traffic Safety Administration (NHTSA). Inspecting the sidewall is the first step in determining your tires’ age.

3. Find Tire Manufacturers Year

After the “DOT” letter, you’ll see a series of letters and numbers. Among these, focus on the last two numbers. These two digits represent the year your tires were manufactured. For instance, if the numbers are “20,” it means the tire was made in 2020, “15” indicates 2015, and “10” denotes 2010. Driving on a tire that is ten years old or more is extremely risky.

FAQ

Conclusion

Summing it up, sidewall tire cracking is a common problem that poses risks to your driving safety. According to the cracking chart, you should limit driving or replace the tires if you see any cracks in the sidewall or dry rot that is deeper than 2mm.

As per DOT and NHTSA instructions, don’t use tires that are older than ten years. Moreover, regular inspection of your tires, maintaining proper inflation, and avoiding extreme temperatures prevent cracking and ensure a smoother journey.
