tireCheck each Tire regularly. In today’s world, the temperature of the earth has shot up considerably in the past few decades, and our summers are much more severe than before. In a similar way, your car may also bear the brunt of the extreme weather. Tires can get overheated easily, causing them to wear out or burst much quicker.

When the Tire gets Hot

Heat can be quite devastating for your car’s tires. When the temperature increases, the air pressure will also increase in your tires. This is because the air molecules get excited and vibrate at a higher frequency. They also space out from each other, which causes the tire to get bigger.

This is why the recommended tire pressure for most standard vehicles is between 30-35 pound per square inch (PSI). Anything over that can contribute to the tire bursting due to heat. Here are some other reasons that you should know about.

Heated Rubber Molecules

Earlier, we talked about how the air molecules get excited and expand, taking the tire with them. However, all materials have these molecules, including the rubber from which the tires are manufactured. When these tires come in contact with excessive heat, the molecules inside the rubber start to get hot and vibrate vigorously. This causes them to contract, rather than expanding.

When this happens, your tires will start wearing out much quicker, and they will also have reduced grip, which makes it dangerous for you. If you keep driving your car in this state, one of your tires is bound to blow very soon. Therefore, it is always advisable to check the tire pressure whenever you leave home, and also check if your tires are too hot to the touch.


Naturally, when you drive your car on the road, it creates a lot of friction with the asphalt on the road. The friction gives the tires their grip, so it is actually useful. However, during the summer, the roads can also get heated, which causes greater friction. As a result, the tires are also overheated and are at a risk of wearing out or bursting.

Can a Tire Blow?

One of the best ways to prevent any heat-related damage to your tires is to park your car in a shaded area. The direct sunlight won’t heat up the tires while your car is parked for a long time. This would keep the tires much cooler, and also prevent them from expanding.

You can also keep a tire pressure gauge in your car and check the pressure level periodically. If you notice that the pressure almost appears to be higher than the level, then you can be sure that the tire is overheating and needs attention.

This concludes our guide on the effect of summer heat on your tires. Make sure to keep an eye on your car’s tires and also prevent them from getting damaged due to overheating. If you have any questions, contact us so we can inspect the tires for you.
