Can Tires Overheat on Hot Roads?

Now that the summer is here, you may be using your car more often for travel. However, did you know that hot weather can affect your tires? In fact, hot weather has more of an impact on your tires than cold weather. There are a variety of reasons for this phenomenon. Plus, our team at Ken’s Automotive & Transmission can explain why hot weather increases your likelihood of a tire blowout and what you can do to avoid these issues this summer.

Can tires overheat on the road?

What Causes Tires to Overheat?

As the temperature rises, the air pressure within your tires increases as well. It is estimated that for every ten degrees Fahrenheit that the temperature rises, tire pressure will increase by one pound. Here are some of the factors that cause tire pressure to increase:

Hot Molecules

Everything is made up of molecules. When molecules overheat, they start to vibrate more and cause expansion. When your air-filled tires heat up throughout the summer, they will expand.

Friction

As you’re driving, your tires rub against the asphalt and cause friction. Friction creates heat and makes your tires hotter during the summer.

Rubber

Since tires are made from rubber, they have a significant chance of expanding. Just like a rubber balloon that has too much air in it, your tires can blow out if too much air is trapped inside. During the summer, as air expands, a blowout could occur. 

How to Avoid a Tire Blowout

Here are some things you can do to prevent a heat-related tire blowout.

Keep Tires Properly Inflated

This summer, be sure to inflate your tires to their appropriate PSI. The appropriate amount of air will vary depending on the car you drive, so check your owner’s manual or inside the driver’s door to get the most accurate numbers. Lastly, always fill to the recommended PSI and not the maximum PSI. 

Let Your Tires Cool Down

If you suspect that your tires are overheating, don’t drive on them. Let them cool down before proceeding. Do not let a little air out so you can continue traveling because your tires will be under-inflated and suffer even more damage. 

Replace Worn Out Tires

If your tires are worn out, they’re more prone to a blowout. Have them replaced before you head out this summer.
