Might be important to note that the temperature is measured in degrees Kelvin. To visualize the effects of the above formula, consider this:

Imagine the relatively small change from 32 degrees F (0 degrees C, 273 degrees K) to 68 degrees F (20 degrees C, 293 degrees K). That is a 7.3% change in temperature, which will get you a 7.3% change in pressure (100 psi to about 107 psi).

The previous statement of the Ideal Gas Law assumes that the volume is held constant. Not exactly true for tires but probably close enough.
