Tire pressure will rise and fall when the vehicle is in use. At the time they gathered the info for the report the numbers may have been correct and not what it may be currently. I am not 100% sure of how they gather that info, it could also be an average of the pressure thruout the month but that would be pretty pointless. IMHO including the tire pressure info is pointless but I guess for the people who dont check it often its a good reminder that your tires may need some more air.ebeno said:
