The tire light should stay off unless one is low on air on my 2008 Dodge Ram
1500. However, I have been an issue when the outside temperature drops
below 45 the light will come on. It will stay on until the air in the tire
warms up or I add air to them. The problem I have is here in Louisiana it
may be 70 degrees one day and 45 the next during the winter.
Tire pressure also changes with the temperature outside. Tire pressure
decreases by about 1 pound per square inch for every 10-degree drop in
outside air temperature.
