or 30°C.
^
Using the tire pressure chart (Figure 1), find the intersection of the hot tire line at the point corresponding to 54°F or 30°C, and read off the value on
the tire pressure change axis. In this case it would be about 9.0 PSI.
^
Compute the actual tire pressure the tires should be filled to:
31.9 + 9.0 PSI = 0.9 PSI.
In this example the tires would need to be filled to 41 PSI to compensate for the seasonal temperature difference and the heat in the tires from the long,
high-speed drive to your dealer.
From these examples you can see that while the "cold" tire pressure specified for the tires is 32 PSI in the Owner's Manual, you may need to inflate the
tires to 41 PSI, or more, depending on seasonal weather conditions and initial tire temperature.
