What are the causes of tire blowouts?

Tire blowouts sometimes have devastating consequences. When a vehicle is in motion and one bursts, it can lead to a frightening accident.

According to the National Transportation Safety Board, at least 2,000 crashes result from blowouts yearly. Awareness of what causes tire blowouts helps prevent these potentially tragic incidents.

Underinflation

One of the primary conditions leading to a blowout is underinflation. When tires lack the proper air pressure, they tend to overheat and weaken. These tires are more susceptible to damage from potholes or debris since they have less cushioning to absorb impacts. Regularly checking and maintaining the correct tire pressure is a sensible safety measure.

Overloading

Overloading a vehicle beyond its recommended weight capacity stresses tires. When tires strain under excessive weight, it leads to extra friction and heat buildup, making blowouts more likely.

Damage and wear

Over time, tire treads thin due to regular driving. Additionally, punctures or cuts from debris, such as shards of glass, may weaken the outer layer. Replacing at-risk tires can avert a disaster.

High speeds

Driving at excessive speeds generates more heat within tires due to greater friction with the road. This may cause the internal components to weaken and eventually fail. Staying under the speed limit improves fuel efficiency and reduces the risk.

Age

Tires have a limited lifespan, regardless of tread depth. Rubber compounds degrade over time, making them less flexible and more prone to cracks. It’s advisable to replace tires that are more than six years old, even if they appear to be in good condition.

Tire blowouts are a prime cause of accidents, occasionally ending in personal injuries. Fortunately, every motorist can play a role in reducing the likelihood of such ruptures.
