chimchim Posted July 15, 2005 Share Posted July 15, 2005 Even though the RX has a tire pressure monitoring system, it's not a replacement for checking your own tire pressure. Here's why: The system does NOT check actual tire pressure, rather it infers RELATIVE pressure between the 4 tires. It does this by sensing the rotational frequencies of the 4 tires. When one tire is spinning at a radically different rate, it probably means that the diameter of the tire is different than that of the other tires... often due to tire pressure. Thus, if you have 4 under inflated tires, the system will not go off. The purpose of this system is really to let you know when you get a flat or a slow leak. Also, the speed sensors are located at the spindle, not on the wheel so rotating the tires will not matter. Quote Link to comment Share on other sites More sharing options...
