Why is 28 PSI Often Viewed as Low Tire Pressure?
Is 28 PSI Low Tire Pressure? Understand Risks and Safety Recommendations
28 PSI is often viewed as low tire pressure because it is below the recommended range for most passenger vehicles. Recommended tire pressures typically range from 30 to 35 PSI. Lower pressures can lead to various issues including poor handling, increased tire wear, and reduced fuel efficiency.
According to the National Highway Traffic Safety Administration (NHTSA), proper tire inflation is crucial for vehicle safety and performance. Maintaining the recommended tire pressure influences vehicle stability and can help prevent tire blowouts.
The reasons for 28 PSI being considered low include potential loss of vehicle control and increased rolling resistance. When tire pressure is low, the tire can flex more than designed. This flexing causes heat buildup, which can deteriorate the tire structure. Additionally, tires with insufficient pressure do not have the optimum surface area for contact with the road, leading to decreased traction.
Tire pressure refers to the amount of air inside a tire, measured in pounds per square inch (PSI). When air leaks or tires degrade over time, tire pressure can drop. Environmental factors, such as extreme temperatures, also affect air pressure. For instance, cold temperatures can cause tires to lose pressure, as air contracts when it cools.
Specific conditions that contribute to low tire pressure include prolonged periods without checking tire inflation, rapid changes in temperature, or neglecting to maintain tires. Many drivers may not inspect tire pressure regularly, leading to unnoticed declines. For example, the temperature drops significantly in winter; this can lead to a natural decrease in tire pressure by about 1 PSI for every 10-degree drop in Fahrenheit.
In summary, while 28 PSI might seem adequate in the short term, it is often insufficient for maintaining optimal vehicle performance, safety, and tire longevity. Regular tire maintenance, including checking pressure, can mitigate risks associated with low tire pressure.
