not sure if they will stay. I have a 19mm bolt cap for my 2019 Jeep Cherokee Trailhawk with 17" factory painted black wheels. The installation guide says 19mm nut cap, which is wrong. My model has screws. I called the manufacturer's rep and said a 19mm nut would fit. However, I went against what he said because I knew he was wrong. The brief installation instructions said to fit snugly and apply hairspray. I think they are meant to stay tight and also lubricated when you install them. We'll have to wait and see if they fall off. I believe they need to be 17mm to fit exactly. Should they fall off due to incorrect installation instructions, I would like them to be replaced free of charge.
