How Does Hot Weather Affect Tire Pressure?

As summer rolls around and temperatures rise, it's essential to pay attention to how the heat affects your vehicle, especially your tires. At Babcock Auto Care in Rochester, MN, we understand that hot weather can significantly impact your tire pressure, which in turn can affect your safety and driving experience. Here’s what you need to know about managing your tire pressure during the summer months.

Understanding Tire Pressure

Tire pressure is the amount of air in your vehicle's tires, measured in pounds per square inch (PSI). Proper tire pressure is crucial for optimal vehicle performance, fuel efficiency, and safety. Under-inflated or over-inflated tires can lead to uneven tire wear, reduced traction, and even tire blowouts.

How Heat Affects Tire Pressure

Temperature has a direct impact on tire pressure. As temperatures increase, the air inside your tires expands, leading to higher pressure. For every 10-degree Fahrenheit increase in temperature, tire pressure can increase by approximately 1 PSI. Conversely, cooler temperatures cause the air to contract, decreasing tire pressure.

The Risks of High Tire Pressure

During the hot summer months, the increased heat can cause your tires to become over-inflated. High tire pressure can result in several risks:

1. Reduced Traction: Over-inflated tires have less contact with the road, which can reduce traction and increase the risk of skidding or hydroplaning.
2. Uneven Tire Wear: High pressure can cause the center of the tire to wear out faster than the edges, shortening the lifespan of your tires.
3. Blowouts: Excessive pressure increases the likelihood of a blowout, which can be dangerous, especially at high speeds.

Monitoring and Maintaining Tire Pressure

Regularly checking and maintaining your tire pressure is essential, particularly during the summer. Here are some tips to help you keep your tires in top condition:

1. Check Tire Pressure Regularly: Use a reliable tire pressure gauge to check your tire pressure at least once a month and before long trips. Make sure to do this when your tires are cool, as heat from driving can give a false high reading.
2. Follow Manufacturer Recommendations: Always inflate your tires to the manufacturer’s recommended PSI, which can be found in your vehicle’s owner’s manual or on a sticker inside the driver’s door.
3. Adjust for Temperature Changes: Remember that tire pressure can fluctuate with temperature changes. Read how to do this below.
4. Inspect for Damage: Hot weather can exacerbate existing tire damage. Regularly inspect your tires for cuts, cracks, and other signs of wear.

Step-by-Step Guide to Adjust Tire Pressure:

1. Gather Necessary Tools: You’ll need a reliable tire pressure gauge and an air compressor or access to one (many gas stations have them).
2. Check Tire Pressure When Tires are Cold: For the most accurate reading, check the tire pressure when your car has been parked for a few hours and the tires are cool.
3. Refer to Manufacturer’s Recommendations: Find the recommended tire pressure in your vehicle's owner’s manual or on a sticker inside the driver’s door.
4. Measure Tire Pressure: Use the tire pressure gauge to measure the PSI of each tire.
5. Adjust Tire Pressure: If tire pressure is too high, let some air out by pressing the center of the valve stem until you reach the correct PSI. If tire pressure is too low, add air using an air compressor until you reach the recommended PSI.
6. Recheck the Pressure: After adjusting, recheck the pressure to ensure it's correct.

Can Tires Adjust on Their Own?

Tires do not adjust themselves. Tire pressure naturally fluctuates with temperature changes, but these changes can lead to over-inflation or under-inflation if not monitored. Therefore, it's necessary to manually check and adjust the tire pressure to maintain safety and performance.
