Your first mistake was lying to him.
Sorry to hear, but you might have been let off with a warning if you were just upfront with him. Once you lie, that opens the door for him to go thru a fine check on your car, instead of a quick once over. As for the fine for each rim, he was playing you for a reaction. See if you were a smart mouth or still hiding anything.
Cops are currently looking for in cabin plug in and play stuff, so be careful people.
