How Can Sidewall Wear Differ in Overinflated Tires?

Overinflated tires exhibit increased sidewall wear due to excessive pressure, leading to an uneven contact patch and heat buildup. This wear affects tire performance and safety.

The sidewall of a tire is designed to support the vehicle’s weight and absorb shock. When tires are overinflated, several factors contribute to increased sidewall wear:

Uneven contact patch: Overinflation causes the center of the tire to bulge outward. This results in a reduced contact area with the road, leading to increased pressure on the sides of the tire. A study by the National Highway Traffic Safety Administration (NHTSA, 2010) found that uneven wear patterns drastically reduce tire lifespan.
Heat buildup: Higher pressure in tires increases friction between the tire and the road surface. This friction generates more heat, which can degrade the rubber compounds in the sidewalls. The Tire Industry Association (TIA, 2019) indicates that excessive heat can lead to a condition known as tire blowout, severely compromising safety.
Loss of elasticity: Overinflated tires lose their ability to flex properly. The sidewalls become rigid and less effective at absorbing shocks from road irregularities. According to a report by the American Society of Testing and Materials (ASTM, 2018), this rigidity contributes to accelerated wear and increases the risk of sidewall cracking.
Reduced traction: The bulging center can lead to reduced traction during cornering. This affects handling and increases the risk of skidding. A study published in the Journal of Transportation Safety & Security (Wang et al., 2021) highlights that poor traction can significantly compromise vehicle control.
Potential sidewall damage: Overinflated tires are more susceptible to damage from road hazards such as potholes. The rigid sidewalls are less able to absorb impacts, leading to cuts or punctures that compromise tire integrity.

In summary, overinflated tires lead to increased sidewall wear primarily due to uneven contact patches, heat buildup, loss of elasticity, reduced traction, and greater susceptibility to damage. Proper tire inflation and regular maintenance are crucial for ensuring tire longevity and safety.
