We used to have inspections, but it pretty much got to be a joke, seems like there got to be two kinds of inspection stations, one would just slap the sticker on the windshield, the other would beat the crud out of the vehicle, case in point Dad tells of taking his late 60's Jeepster in for inspection, the inspector gets going about 30 and jams on the brakes, trying to lock up the wheels, keeps doing this until he gets all four wheels to lock up, then refuses to pass it due to the brakes. Law enforcement can issue tickets for unsafe equipment (I think they have to have a reason to pull you over first) and we do have an occasional safety check point, where they check the basic safety stuff(lights horns etc.)
If you really wanted to fight it contact the tire manufacturer,they may be able to help. about 15 years ago, on the circle tracks here, Hoosier GT street radials where the tires to run(rules said it must be a DOT street tire), some tracks reused to let them run the GTs saying that they weren't street leagle, rumor was that if the track refused the GTs, that you could contact Hoosier and the track would be getting a call from one of Hoosiers lawyers.
