I have looked through the laws before and my friend is on the Irvine PD so i had him explain it all to me also. That guy on 46's was blowing smoke up your ass. The tires cant stick out the sides more than 2" and after a certain height you need mudflaps, the middle of your headlights have to be like 52 or 54" inches from the ground, and they also measure your frame but im not sure that that limit is I sure somewhere around 30". Theres probably more than this too.
