Hot weather can cause tires to degrade faster, leading to reduced traction, increased stopping distances, and a higher risk of blowouts. In extreme cases, overheated tires can even lead to accidents, making it essential to understand what happens to tires in hot weather.
The Science Behind Tire Degradation
When tires are exposed to high temperatures, the rubber compound begins to break down, causing the tire to lose its elasticity and flexibility. This can lead to a range of issues, including cracks in the sidewall, tread separation, and increased wear on the tire’s surface. As the tire degrades, its ability to grip the road is compromised, making it more difficult to control the vehicle.
In this article, we will explore the effects of hot weather on tires, including the risks of tire failure, how to identify signs of tire degradation, and tips for maintaining your tires in hot weather.
What Happens to Tires in Hot Weather
As the temperature rises, it’s essential to consider the impact of hot weather on your vehicle’s tires. Extreme heat can cause significant damage to your tires, leading to reduced performance, decreased safety, and even tire failure. In this article, we’ll delve into what happens to tires in hot weather, the consequences of neglecting tire maintenance, and provide tips on how to protect your tires from the heat.
The Effects of Heat on Tire Components
Tires are made up of various components, including rubber, fabric, and steel. When exposed to high temperatures, these components undergo significant changes that can affect the tire’s overall performance and durability.
Rubber Compounds
The rubber compound in tires is designed to provide traction, flexibility, and durability. However, when exposed to high temperatures, the rubber compound can:
- Softens, leading to a loss of traction and increased stopping distances
- Becomes more prone to cracking and damage
- Undergoes a process called “thermal degradation,” which can cause the rubber to break down and lose its strength
Fabric and Steel
The fabric and steel components in tires provide strength, stability, and support. In hot weather, these components can:
- Expand and contract, causing the tire to become misshapen and lose its optimal shape
- Weaken, leading to a higher risk of tire failure
- Become more susceptible to corrosion, which can further compromise the tire’s integrity
Consequences of Neglecting Tire Maintenance in Hot Weather

Underinflated tires are more susceptible to heat damage. Check your tire pressure at least once a month, and before long trips. Use a tire pressure gauge to ensure the pressure matches the recommended level, as specified in your vehicle’s owner’s manual.
Inspect Tires Regularly
Regularly inspect your tires for signs of wear, damage, or uneven wear patterns. Look for:
- Cracks in the sidewall or tread
- Bulges or blisters on the sidewall
- Uneven wear patterns, such as feathering or cupping
- Tread depth, ensuring it meets the minimum recommended level
Rotate Tires
Regular tire rotation can help distribute heat evenly across the tires, reducing the risk of uneven wear and damage. Refer to your vehicle’s owner’s manual for the recommended tire rotation pattern.
Use Tire Shades or Sunshades
When parking your vehicle in direct sunlight, use tire shades or sunshades to block the sun’s UV rays and reduce heat buildup.
Choose the Right Tires
Select tires that are designed for high-temperature environments, such as summer tires or high-performance tires. These tires are formulated to withstand the heat and provide better traction and handling.
Avoid Overloading
Overloading your vehicle can put excessive stress on your tires, increasing the risk of heat damage and tire failure. Ensure you’re not exceeding your vehicle’s recommended weight capacity.
Drive Smoothly
Avoid aggressive driving, such as rapid acceleration, braking, and cornering, as it can generate excessive heat and stress on your tires. Drive smoothly and maintain a consistent speed to reduce heat buildup. (See Also: Are Chains Required On All 4 Tires)
