My tire pressure light flashed for a while and then remained lit for several minutes during a several-hundred-mile roadtrip a few days ago. The vehicle did not pull, drag, or show any sign of tire problems, and when I checked the pressure on all four tires the next morning they were fine. The next day, the same thing happened again after another several hundred miles. This time I pulled over within a few minutes and checked all four tires - good pressure on all of them again. I couldn't check the spare since I had a bunch of luggage loaded. Can't imagine it would help anyway since my tire gauge tops out at just 50 psi. What is my tire pressure light telling me??? If I could figure out what was wrong, I would fix it!
