When summer rolls around and the temperature rises, it’s not just your air conditioner that needs attention—your tires do too. Hot weather can have a significant impact on tire wear and overall tire health. The combination of high temperatures, increased road friction, and long hours of driving can cause your tires to degrade faster than during cooler months. Understanding how heat affects your tires and taking steps to prevent excessive wear can extend their lifespan, improve safety, and save you money on replacements. Here’s what you need to know about how hot weather impacts tire wear and how to protect your tires during the warmer months.
1. The Effect of High Temperatures on Tire Pressure
As temperatures rise, the air inside your tires expands, causing the tire pressure to increase. This can be a problem, especially if your tires are already overinflated. Too much pressure can lead to uneven tire wear, reduced traction, and an increased risk of a blowout. On the other hand, if tires are underinflated, they can become hotter because the friction between the tire and the road increases, leading to further tire damage.
- What to do: Make sure to check your tire pressure regularly, especially before long trips in hot weather. Use a tire gauge to ensure the tires are inflated to the manufacturer’s recommended levels, which can usually be found on the driver’s side door frame or in the owner’s manual. Adjust the pressure accordingly to maintain optimal performance and prevent unnecessary wear.
2. Increased Road Friction and Tire Wear
Hot weather increases the temperature of the road surface, which leads to higher levels of friction between your tires and the pavement. This friction causes your tires to wear out more quickly, particularly the tread. In addition, longer periods of driving during the summer can cause the rubber in your tires to soften and break down, leading to faster wear.
- What to do: Reduce excessive heat buildup by driving at moderate speeds. Avoid sudden acceleration or hard braking, which increases friction. When possible, take breaks during long trips to allow your tires to cool down. Also, ensure your tires are properly aligned and balanced to minimize uneven wear.
3. Tire Overheating and Its Risks
As tires heat up in the summer, they become more prone to damage. Overheating can cause the rubber to break down, leading to dry rot, cracks, and weakened sidewalls. This not only shortens the lifespan of your tires but also makes them more susceptible to blowouts, which can be particularly dangerous on highways or when driving at high speeds.
- What to do: Check your tires for visible signs of damage, such as cracks, bulges, or dry spots, which could indicate that they’ve been exposed to excessive heat. If you notice any of these issues, it may be time for a tire replacement. Regular tire maintenance and inspections can prevent overheating and keep your tires in good condition.
4. How Hot Weather Accelerates Tread Wear
The high heat from the road surface causes your tire tread to wear down faster. The tread is responsible for providing grip and traction, which is crucial for safe driving, especially during rain or snow. As the tread wears away more quickly in the summer heat, it can compromise your car’s handling, braking ability, and overall safety.
- What to do: Check the tread depth of your tires regularly. The easiest way to check is by using the penny test—insert a penny into the tread with Lincoln’s head upside down. If you can see the top of Lincoln’s head, it’s time to replace your tires. Regular tire rotation can help ensure even wear and prolong the life of your tires.
5. Avoiding Tire Damage From Road Hazards
Hot weather can exacerbate the impact of road hazards such as potholes, rocks, or debris. As the pavement heats up, it can soften, making it more likely for potholes and other road hazards to cause damage to your tires. Hitting a pothole or running over debris can cause punctures, cuts, or even blowouts, especially when tires are already weakened by heat.
- What to do: Avoid driving over potholes or sharp objects on the road. Slow down when driving on poorly paved or rough roads, and be cautious in areas where debris is present. Consider investing in a tire with a higher durability rating if you live in an area with particularly rough roads.
6. Choosing the Right Tires for Hot Weather
Not all tires are created equal, and some are designed to perform better in hot conditions than others. Summer tires, for example, are designed to handle high temperatures and provide optimal grip and performance during the warm months. They are made with a rubber compound that is more heat-resistant than all-season or winter tires.
- What to do: If you live in an area with consistently hot weather, consider switching to summer tires or tires that are specifically designed for high temperatures. These tires will perform better in the heat and offer greater safety and longevity. If you use all-season tires, make sure they are well-maintained and checked regularly for wear.
7. The Importance of Regular Tire Maintenance
Maintaining your tires in the summer months is essential for ensuring their longevity and performance. Regular tire checks, including pressure, alignment, and tread depth, will help you identify potential issues early on before they become serious problems.
- What to do: Schedule regular tire inspections and rotations, and have your alignment checked at least once a year. Keep your tires properly inflated, monitor their tread depth, and be vigilant about inspecting them for damage. By staying proactive, you can avoid unexpected tire failures and keep your car running smoothly.
8. Protect Your Tires This Summer
Hot weather poses several challenges for your vehicle’s tires, but with proper care and maintenance, you can minimize the risks and extend their lifespan. Regular tire inspections, maintaining proper tire pressure, and driving carefully in extreme heat are key to ensuring your tires perform optimally during the warmer months. Take the time to care for your tires, and they’ll take care of you, ensuring a safer, smoother ride all season long.
