You know how flats happen, but have you ever wondered what causes a tire to be more or less susceptible to punctures?

Understanding the science behind what causes a tire to puncture not only helps with prevention but also equips vehicle owners with knowledge to better maintain their tires. In this article, we'll explore the common causes of tire punctures and how you can protect your investment.

What Determines a Tire's Durability Against Punctures?

Pressure Level: Underinflation increases the likelihood of punctures because low tire pressure causes the tire to flex more than intended during operation. This additional flexing generates more heat and stress on the tire's sidewalls and tread, making them more likely to incur damage from road debris or sharp objects. An underinflated tire also has a larger contact patch with the ground, which leads to increased wear and a greater chance of encountering hazards. The combination of increased heat, stress, and road contact heightens the risk of tire failure. This is why it's recommended that you check and correct your tire pressure at least once a month, if not more frequently.

Tread: Lower tread depth reduces a tire's ability to absorb impacts and provide traction, making it more susceptible to punctures. Tread is designed to channel water away and maintain grip on the road, and when it wears down, the tire has less surface area to disperse forces evenly. This can lead to increased stress on the tire's structure, especially when encountering sharp objects or rough terrain. Additionally, worn tires are more likely to lose air pressure, which can further exacerbate the risk of punctures and blowouts.

Age: As tires age, the rubber compounds harden and lose elasticity. This can lead to increased brittleness and make them more susceptible to damage from road debris and sharp objects. Old tires are less able to absorb impacts and deform around sharp objects, making them more susceptible to punctures and cuts. Additionally, the aging process can degrade the tire's materials, leading to cracks and weakened areas that are more prone to failure. This deterioration from age leads to a reduced ability to withstand impacts and an increased vulnerability to punctures, even if the tread depth appears sufficient. Regularly checking the age of tires and replacing them as they age is crucial for maintaining safety and performance on the road.

Preventive Measures

To minimize the risk of tire punctures, implement these preventive measures:

• Inspect Tires Regularly: Check your tires for visible damage, foreign objects, and tread wear regularly.
• Maintain Proper Inflation: Use a reliable gauge to check tire pressure at least once a month and before long trips.
• Rotate Tires: Regularly rotate your tires to ensure even wear and extend their lifespan.
• Avoid Road Hazards: Stay vigilant while driving to avoid potholes and debris when possible.

Is It Possible for a Brand New Tire to Puncture?

Yes. Even if you have a brand new tire that is properly inflated, it can get a puncture. There are some nasty hazards out there, and hitting a nail at the right angle and speed can result in a flat. Some tire manufacturers include road hazard protection with their tires, so if this happens, the repair will be covered or a replacement tire will be granted at a prorated price. There are run-flat tires that allow you to keep driving after your experience a puncture for an extended amount of time. This way, you can get off the road, over to a tire shop, or back home if you're close enough. Depending on the tire manufacturer, the recommendations on when repairs are permittable (or if they aren't) for run-flats will vary.
