Sorry to hear about your wheels. Get some wheel locks now; I knew rim thieves when I was a teenager (one died running from the cops), It doesn't matter what kind of wheel locks; when thieves sees them, the last thing they want to do is draw attention to their crime and removing wheel locks are sometimes very noisy, so they move to the next victim..
Just don't let anyone tighten them with an impact wrench.. You'll know why I said that if they do..
