UPDATE: They are starting to peel off. After long drives, the system detects a TPMS malfunction, which is annoying. It happened 3 times. The warning disappears after restarting the vehicle. I DO NOT RECOMMEND. UPDATE: I went to Discount Tire Co and using their TPMS device I was able to activate these sensors and pair them to my truck. They also did it for free. Before sending them back, try them out at a tire shop. The small retraining tools sold on Amazon are not powerful enough to trigger the sensors. F150FX4, 2012
