As I was driving to the airport this morning, I got a low tire pressure warning. Of course I never put my pressure gauge in my car, so I couldn't check it at the airport, and I won't see the car again til Friday. Assuming the tire(s) still have air by Friday morning, is there a way to get the computer to tell you which tire is low? None of them look visibly low (although I haven't checked pressure for a while), and they all look approximately the same level.
Remember...looking at a low profile tire will never give you an idea of a tire getting low. My recommendation is that you check your pressure (cold) at least once a month and set it to 32/33 PSI. Also check it during weather changes...remember for every 10 degree change in temperature, your tire pressure will adjust 2-3 PSI (checked cold -- i.e. sitting for at least 4 hours). The only other thing would be that you have a defective tire sensor in one of the tires...as usual, another gimmick and another item that can break.
No there is no way to have the computer tell you which tire is low, you're going to have to use the Obama method and check them all with a pressure gauge.
