Tire Pressure Calculator





Formula

The formula to calculate the change in tire pressure with a change in temperature is:

\[ TP = OTP \pm OTP \times \left(\frac{TC}{10}\right) \times 0.02 \]

Where:

Does Tire Pressure Change with Temperature?

Yes, tire pressure does change with temperature. Since tires are filled with air, and air follows the laws of thermodynamics, the air pressure must change when the temperature of the air changes. These laws are known as the ideal gas laws. As temperature increases, pressure will also increase. Conversely, as temperature decreases, tire pressure will also decrease.

Example Calculation

Let's assume the following values:

Step 1: Calculate the Change in Pressure:

\[ \text{Change in Pressure} = 35 \times \left(\frac{10}{10}\right) \times 0.02 = 35 \times 0.02 = 0.7 \text{ PSI} \]

Step 2: Calculate the New Tire Pressure (TP):

\[ TP = 35 + 0.7 = 35.7 \text{ PSI} \]

The new tire pressure is 35.7 PSI.
