The summer heat has topped 100 degrees Fahrenheit in many locations around the country this year. Heat is your tire’s worst enemy, and the hotter a tire gets, the higher the risk of failure. Knowing some common causes of tire blowouts can help ensure that you and your family remain safe as you travel. Extreme temperatures can force tires to building pressure and overheat more readily. Additionally, increased friction, driving at high-speeds, and frequent braking during periods of very high temperatures can cause the tire to heat up beyond their design ratings. This can eventually lead to a tire blowout when you least expect it.

Many newer cars come equipped with tire pressure sensors; however, whether or not you have them, checking to make sure that tires are inflated to manufacturers’ specifications can ensure your safety. Defective sensors may not be noticed until it is too late. Under-inflated tires increase the risk of tire blowouts because they tend to run hotter in general. Also, tires that are worn out, have cracks, or are generally older can fail in hotter weather as well.

An important note is that not all tires are created equal when it comes to temperature ratings. Just like size and weight ratings, temperature ratings show a tire’s resistance to heat and its ability to dissipate heat, when tested under controlled laboratory test conditions. If you live in a much warmer climate, choosing tires that specify higher temperature ratings can potentially save you in the long run.

Finally, plastic valve caps are a better choice than metal caps. In severe heat, metal caps can potentially weld to the tire valve itself, making it nearly impossible to refill air pressure. There are many causes of tire blowouts, but with a few simple checks, you can enjoy the summer heat.
