vince^_^ 11/11/2010Are you certain that the new tires are equipped with a Tire Pressure Sensor? Even if the tires have a correct tire pressure the PCM/ECU based on the signals from your TPS and if your tires is not equipped with that sensor or the sensors aren’t activated the tire pressure will come on. Did you also purchase a new spare tire? Sometime even if your 4 tires is equipped with TPS (tire pressure sensor) and its working but your spare tire doesn’t have any TPS your tire pressure will come on.
