I'm in NJ, by Toms River, and personally I think the tints are worth it. It's a $56 ticket (including convenience charge for paying online) and in my experience, and the experience of my friends, they're almost a get out of jail free card. Getting pulled over for a more serious offense (speeding, failure to stop, illegal turn) can usually be knocked down to a simple tint ticket if you leave your window up a little bit, as not to hide the tint from the officer, and be completely cooperative and cool with the cop that pulls you over. I've gotten two tint tickets this year, one resulting from doing 50 in a 30, and another from doing 90 in a 45 construction zone on the parkway here. I've honestly never heard of someone getting pulled over and getting a ticket for tints alone. If you do get pulled over because of your windows, I can promise you the cop is just checking to make sure nothing illegal is going on (i.e. you don't have a kilo of black tar on your passenger seat), and as long as everything is square, you'll be on your way.
So, aside from just the convenience of having them done for preference reasons (solar control, privacy, etc), they can be good for other things too. Just my opinion though. At the end of the day, they are still illegal.
