What are the causes of tire blowouts in summer?

[LaMorgan]

Causes of tire blowouts include low tire pressure, overinflation, incorrect installation, poor maintenance, tire wear and aging, sidewall bulges, manufacturing defects, and severe impacts. Below are additional details: Measures to prevent tire blowouts: Replace tires in a timely manner, perform proper wheel alignment and tire balancing, rotate front and rear tires, maintain normal tire pressure, and avoid speeding. How to handle a tire blowout: Hold the steering wheel firmly and adjust the direction gently; avoid jerking the steering wheel repeatedly or slamming on the brakes. Wait for the vehicle to slow down gradually before steering lightly. Set up a warning triangle behind the vehicle to prevent secondary accidents.

I have deep feelings about summer tire blowouts, which mainly boil down to three words: thermal expansion and contraction. When temperatures rise, the air inside the tires expands significantly. If the tire pressure is already on the high side, the pressure can skyrocket. Asphalt roads become scorching hot under the sun, and rubber tires running on them are like pancakes—not only does grip decrease, but aged and cracked tires are most likely to burst suddenly at high speeds. Once, I was on a long-distance drive, and at noon when the sun was at its fiercest, I hit a speed bump too hard—BAM!—it tore the sidewall right open. So before heading out in summer, you must check the tire wear indicators. Tires with worn treads are more prone to deformation when heated, especially when fully loaded on highways—overloaded tires can fail immediately. It's recommended to keep summer tire pressure 0.1-0.2 bar lower than the standard and avoid driving during the hottest midday hours.

Tire blowouts in summer are almost a common occurrence, with the main issue being uncontrolled tire temperature. Roads exposed to the scorching sun can easily reach 60 degrees Celsius, and the high temperatures generated by prolonged high-speed friction can soften the rubber to the consistency of playdough. Add to that some tires that haven't been replaced in five or six years, with tiny cracks all over the sidewalls, making them completely unable to withstand such torture. I remember last August, a friend of mine was on a family trip with the trunk packed full of luggage when suddenly—bang!—a tire blew out on the highway. Later inspection revealed it was a combination of overloading and tire aging. Additionally, seemingly insignificant debris like broken glass or metal shards on the road can become sharper in the heat, easily puncturing the tires. So, a special reminder: in summer, regularly pick out stones stuck in tire treads, check tire pressure monthly, and ideally, don't let tires exceed six years of use.

Summer tire blowouts are no accident; the key lies in failing to control temperature and condition. During the day, tire temperatures can easily soar to 70-80 degrees Celsius. If there are bulges or areas that have been patched multiple times, the high temperatures can cause these weak spots to burst open. I learned this the hard way a couple of years ago—once, in a rush at noon, I hit the road without checking, and within half an hour, my rear tire went flat. Upon stopping, I found it was due to a hidden injury from scraping the curb earlier. Many car owners overlook this: right after the car has been baking in the sun, it's particularly dangerous to start driving immediately. It's best to let the tires cool down a bit before hitting the road. If you notice abnormal vibrations or smell rubber, pull over immediately to check.
