- TPMS Malfunction
Understanding these factors is crucial in maintaining tire health and ensuring safety on the road.
-
Reduced Tire Pressure: Reduced tire pressure occurs when a tire loses air due to punctures, leaks, or natural air permeation. Tires typically lose 1-2 psi (pounds per square inch) per month and this can trigger the low tire pressure light. According to the National Highway Traffic Safety Administration (NHTSA), driving on under-inflated tires can decrease fuel efficiency by 3-4% and increase the risk of tire blowouts.
-
Temperature Changes: Temperature changes can result in decreased tire pressure. For every 10°F drop in temperature, tire pressure typically decreases by 1-2 psi. This phenomenon occurs because air contracts when it cools. A study by the Rubber Manufacturers Association (RMA) illustrates that winter months often see a rise in the number of low tire pressure indicators due to this natural correlation.
-
Tire Damage: Tire damage, such as cuts, punctures, or sidewall bulges, can cause a loss of air pressure and trigger the warning light. Damaged tires cannot hold air as effectively, leading to gradual or rapid deflation. The American Automobile Association (AAA) encourages drivers to routinely check tire integrity to avoid such issues that can compromise safety and longevity.
-
TPMS Malfunction: A malfunction in the tire pressure monitoring system (TPMS) may also turn on the low tire pressure light. This can occur if the sensors are damaged, dead, or if there is a fault in the system itself. The TPMS is a safety feature designed to warn drivers before a tire becomes significantly under-inflated.

Why Is Tire Pressure Maintenance Important for Safety?
Tire pressure maintenance is crucial for safety because it directly affects vehicle handling, braking, and overall vehicle stability. Maintaining the correct tire pressure ensures optimal contact between the tires and the road, which enhances traction and reduces the risk of accidents.
According to the National Highway Traffic Safety Administration (NHTSA), properly inflated tires can improve fuel efficiency and prolong tire life, contributing to overall safety on the road. Under-inflated tires can lead to tire blowouts, while over-inflated tires can reduce traction and increase stopping distances.
There are several underlying reasons why tire pressure maintenance is vital. Firstly, air pressure in tires naturally decreases over time, often due to temperature changes. Additionally, driving conditions, such as rough roads or heavy loads, can cause tire pressure fluctuations. Furthermore, tires can lose air through small punctures or leaks, which can go unnoticed until a significant issue arises.
Tire pressure is measured in pounds per square inch (PSI). The recommended PSI for most passenger vehicles ranges from 30 to 35 PSI, but this can vary based on the vehicle type and manufacturer specifications. Under-inflation occurs when the tire pressure falls below this recommendation, while over-inflation occurs when it exceeds the advised level. Both conditions can compromise safety.
The mechanisms involved in tire pressure maintenance include the tire’s ability to support the weight of the vehicle and ensure proper contact with the road. When tires are under-inflated, their sidewalls flex excessively, generating heat and increasing the risk of failure. Conversely, over-inflation causes the tire to become rigid, reducing its ability to absorb shocks and improving chances of losing traction on wet or uneven surfaces.
Specific conditions that contribute to tire pressure issues include seasonal temperature changes, frequent short trips that prevent tires from warming up, and the vehicle’s load capacity being exceeded. For example, a vehicle fully loaded with passengers and cargo may experience a decrease in tire pressure if not adjusted accordingly. Regular checks and adjustments can help mitigate these risks and enhance driving safety.
