The 55 model is a simplified system, it only handles 4 tires and PSI readings up to 80 plus the temperature, better suited for a regular car, truck, or SUV. The 66 model is more advanced in features (alarms and memory ability), 22 tires can be programmed up to 232 PSI with temperature, and has a signal booster.
