Flat tires occur due to various factors that can cause air loss from the tire. Understanding these causes helps in preventing future occurrences.

Punctures from sharp objects
Valve stem failure
Tire wear and damage
Improper inflation
Environmental factors
Manufacturing defects

These causes represent a range of scenarios that can lead to a flat tire. Some drivers may hold conflicting views about maintenance and road safety, believing that flat tires are simply a part of ownership or driving, rather than preventable outcomes.

Punctures from Sharp Objects:
Punctures from sharp objects lead to flat tires when nails, glass shards, or other debris penetrate the tire. This can happen on any road surface, especially in urban areas. According to the National Highway Traffic Safety Administration (NHTSA), punctures are a leading cause of tire failure. Regular tire inspections can help identify punctures before they cause air loss.
Valve Stem Failure:
Valve stem failure is another common cause of flat tires. The valve stem is a small component that allows for inflation and deflation of the tire. Over time, exposure to weather and road conditions can weaken it. A study published by the Rubber Manufacturers Association (RMA) in 2018 showed that over 10% of all tire failures were due to valve stem issues. Replacing old or damaged valve stems can prevent this issue.
Tire Wear and Damage:
Tire wear and damage contribute significantly to flat tires. Tires experience wear due to friction with the road. Uneven wear can result from improper alignment or suspension issues. The Tire Industry Association (TIA) states that tires should be replaced when tread depth falls below 2/32 inch. Regularly rotating tires and checking tread depth can prevent excessive wear.
Improper Inflation:
Improper inflation causes tires to lose their structural integrity. Under-inflated tires generate excess heat, increasing the risk of blowouts. Over-inflated tires may lack traction and wear unevenly. The American Automobile Association (AAA) recommends checking tire pressure monthly. Maintaining the correct tire pressure enhances safety and longevity.
