Similar thing happened with me a few years back with another car. Big pothole on RT208 North...blew out both left side tires and bent both wheels. My cousin is a lawyer so I had her contact the authorities and they're excuse was "we didn't know about it until now, so it's not our problem". Fuckin thing was fixed the next day and I was out almost $1000 for 2 wheels and tires.
Good luck man, its gonna be a bitch to collect from the State.
