Tire sidewall cracks are a common issue that many drivers face, but not everyone knows what causes them. These cracks, also known as “dry rot,” can affect the performance, safety, and longevity of your tires. Additionally, for car owners, it’s crucial to get your tires checked at a Mazda service center in Mussafah to ensure they’re in top condition.
Let’s dive into the primary causes of tire sidewall cracks and the best ways to avoid them.
1. Exposure to UV Rays
One of the main reasons behind what causes tire sidewall cracks is prolonged exposure to ultraviolet (UV) rays. Just like your skin can get damaged from too much sun, so can your tires. UV rays weaken the rubber compounds, causing the tire material to dry out and eventually crack.
How to Prevent UV Damage:
- Parking in shaded areas or using a car cover can significantly reduce UV exposure.
- Regularly apply tire protectant products that contain UV inhibitors.
- If you’re leaving your car parked for extended periods, consider moving it occasionally to reduce uneven UV exposure on the tires.
2. Age of the Tires
Even if your tires look fine, age can play a big role in causing tire sidewall cracks. Over time, the rubber in tires naturally degrades. This aging process can occur even if the tires are not heavily used. Most tires have a lifespan of 6-10 years, depending on usage and storage conditions.
How to Prevent Aging-Related Cracks:
- Regularly inspect your tires for signs of aging, especially if they are more than five years old.
- Store tires in a cool, dry place away from direct sunlight and extreme temperatures if they are not in use.
3. Under-Inflation
Driving on under-inflated tires is another key factor in what causes tire sidewall cracks. When your tires are under-inflated, more stress is placed on the sidewalls as they have to flex more to support the weight of your car. Over time, this extra stress can lead to cracks.
How to Prevent Under-Inflation Issues:
- Check your tire pressure at least once a month and before long trips.
- Keep an eye on your vehicle’s tire pressure monitoring system (TPMS), and don’t ignore any alerts.
- Use a tire inflator to keep your tires at the manufacturer’s recommended pressure level.
4. Chemical Exposure
Tires can also crack due to exposure to harsh chemicals and solvents. This can occur if tires come into contact with cleaning products, oil, or industrial chemicals. These substances can break down the rubber compounds, leading to cracks and premature wear.
How to Prevent Chemical Damage:
- Use tire-friendly cleaning products when washing your car.
- Keep tires away from chemicals like gasoline, oils, and harsh detergents.
- If you spill any chemicals on your tires, rinse them off immediately with water.
5. Overloading the Vehicle
Overloading your vehicle can be another contributor to what causes tire sidewall cracks. When your car is carrying more weight than the tires are designed to handle, it can cause the tires to flex excessively, putting undue strain on the sidewalls.
How to Prevent Overloading:
- Always check the load capacity of your tires, usually found on the sidewall or in the vehicle’s manual.
- Avoid exceeding your vehicle’s Gross Vehicle Weight Rating (GVWR).
- If you frequently transport heavy loads, consider investing in higher load-rated tires.
6. Poor Driving Habits
Aggressive driving, such as sharp turns, sudden braking, and fast acceleration, can also lead to tire damage and cracking. These actions put additional pressure on your tires, especially the sidewalls, which aren’t as reinforced as the tread.
How to Improve Driving Habits:
- Drive smoothly and avoid aggressive maneuvers that can put stress on your tires.
- Be cautious when driving over potholes, curbs, and rough terrain as these can increase the likelihood of tire damage.
When Should You Replace Cracked Tires?
If you notice sidewall cracks on your tires, it’s essential to take immediate action. While minor surface cracks might not pose a significant threat, deeper cracks indicate a weakened tire structure. Here’s when to replace your tires:
- Visible deep cracks: If the cracks are deep enough to expose the inner layers of the tire, replace them immediately.
- Aging tires: Even without visible cracks, tires older than 6-8 years should be replaced.
- Frequent air loss: If your tires are losing air pressure frequently, it’s a sign they might need replacing.
Don’t wait until it’s too late. If you’re unsure about your tires’ condition, visit a professional for an inspection. Finding a tyre shop near me that offers quality service and affordable tire options is always a smart move for proactive car owners.
Conclusion
Understanding what causes tire sidewall cracks is the first step toward preventing them. From exposure to UV rays and chemical damage to poor driving habits and under-inflation, several factors contribute to tire degradation. However, with regular maintenance and proactive care, you can extend the life of your tires and ensure a safer driving experience.
