On Labor day I bought and installed a set of RX8 wheels & rubber with NO sensors. The missing sensors was part of the deal. The stock rubber was mounted on the wheels so I just assumed the kid wouldn't lie about such a thing. I ended up being assured this was the case because the light appeared on my dash within minutes of the swap. I also kept getting a series of beeps every once and awhile which I assumed was all related. Anyhow, until last night I never got around to checking the tire pressures on the new tires. They were low - so I filled them up and took the car for a ride. For some reason, the light on the dash disappeared. It was still missing during my drive to work this morning which is a good 20 minute drive which I feel is enough time to sort it's self out. What gives?
