Why Does Tire Pressure Increase with Heat?

Temperature increases cause tire pressure to rise due to the properties of gases. When tires heat up, the air inside them expands, leading to higher pressure.

According to the National Highway Traffic Safety Administration (NHTSA), “Tire pressure increases as a result of the tire’s heat from driving and ambient conditions.” This illustrates the direct relationship between temperature and tire pressure.

The underlying reason for increased tire pressure involves the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature when the volume is constant. As the tires rotate and generate friction, they heat the air inside. This heat causes the air molecules to move more rapidly, increasing the pressure.

In technical terms, this process can be attributed to thermal expansion. Thermal expansion occurs when materials change in size or volume due to temperature changes. In this case, the air in the tire expands as it warms up, which increases the pressure within the tire.

When driving conditions contribute to tire heat, several factors come into play. For example, driving at high speeds generates more friction and heat, leading to greater increases in tire pressure. Additionally, underinflated tires can create excess heat as they flex more during travel, resulting in further pressure increases. Similarly, driving in high temperatures or on hot pavement can exacerbate this effect.

In summary, tire pressure rises with heat due to the thermal expansion of air inside the tires. Factors such as speed, road conditions, and initial tire pressure all influence how much pressure increases. Regular tire maintenance, including checking tire pressure when tires are cold, is essential for safety and performance.

How Can You Adjust Tire Pressure for Hot Weather Conditions?
