Why Are Screws Always the Ones Puncturing Tires?

The threads of screws can easily embed into tires when run over. Common tire repair methods are as follows: 1. Traditional Plug Method (External Repair): This is a more primitive method. The principle involves using a sharp tool like an awl to enlarge the puncture hole, then inserting a rubber strip coated with adhesive into the hole. It's simple, very low-cost, and quick, requiring no separation of the tire from the rim or wheel balancing. The downside is obvious: enlarging the hole with an awl increases the damaged area, and this method isn't very durable, often leading to air leaks. (This method is not recommended) 2. Patch Repair (Internal Repair): This is the most common method, used by most tire repair shops. The tire is separated from the rim, the damaged area inside the tire is sanded to help the adhesive bond better, then the debris is cleaned off. Special tire repair adhesive is applied to the damaged area and its surroundings, a patch is pressed firmly onto the spot, and another layer of adhesive is applied to complete the repair. 3. Mushroom Plug Repair (Internal Repair): The mushroom plug is currently the most advanced tire repair method, also an internal repair. It requires separating the tire from the rim, and wheel balancing is necessary after repair. The difference between the mushroom plug and the patch method is that the mushroom plug can effectively fill the gaps in the puncture hole, preventing further damage to the affected area.

As someone who frequently commutes by car, I've noticed that screws are indeed a common culprit for punctures. The main reasons are the abundance of construction sites—screws often scatter everywhere during road repairs or demolition work. Their sharp shape and threaded ends allow them to firmly pierce the rubber layer, making them hard to dislodge. Additionally, tire treads tend to trap these objects, unlike other debris such as broken glass or small stones, which are more likely to slide away. During daily driving, it's best to avoid driving over unknown areas, especially parking lots or construction zones. Regularly checking tire pressure and appearance can help detect issues early and prevent roadside breakdowns. Another factor is the delayed cleanup of road debris, which is why I choose to avoid hazardous routes to ensure safety.

After decades of driving, I've found that screws are particularly suited for puncturing tires due to their physical properties. Their material is typically hard and resistant to bending, unlike plastic debris which may shatter; structurally, their sharp points and threads increase friction, allowing them to penetrate the tire surface. Screws found on roads often come from loose vehicle parts or construction residue, and with the large contact area of tires at high speeds, they are easily picked up. Compared to other sharp objects like nails, screws are more commonly encountered due to their wide range of applications, such as furniture assembly or mechanical fastening. It's advisable to slow down when passing through suspicious road sections to minimize the risk.

In automotive repair experience, screw punctures are quite common. Small and sharp, they roll into the tire tread from the road surface and embed themselves, making them hard to detect. Causes include uncleared construction debris or parts falling off vehicles. Tire rubber is soft and easily pierced, and the unique shape of screws makes them more likely to cause leaks compared to blunt objects. Prompt treatment can prevent further damage.

Once I had a flat tire and found out it was caused by a screw. Apparently, I ran over a loose screw while parked by the roadside—its small, sharp shape easily punctured the tire tread. Poor road maintenance leads to the accumulation of such debris, especially in industrial areas or near new construction sites. Screws, with their high density and hardness, are common culprits. When driving, stay alert to avoid potential hazards, and make it a habit to scan the ground around your parking spot before setting off.

From an automotive safety perspective, the high puncture rate caused by screws is due to their ubiquitous presence in the environment. Construction activities, vehicle vibrations, or accidents can all lead to screws being scattered on road surfaces, and their design facilitates penetration into rubber. Tire treads provide traction but also collect debris, while the shape of screws allows them to remain lodged in place, causing air leaks. For prevention, I recommend choosing routes that avoid construction zones, not parking over debris, and performing regular tire maintenance to extend their lifespan. Paying attention to such small details can significantly reduce the risk of tire blowouts.
