I really don't understand why everyone gets so worked up. The sky isn't going to fall- either from running CTs, or from someone trying to ban them. Not gonna happen, period. There are two issues to consider:
-Insurance companies. Does YOUR policy (not your friend's, cousins, brother in laws, etc.) policy state anywhere in it that a CT is not allowed on your bike? Does it state anywhere that only MC tires are allowed? No? Then they have no right to deny a claim.
-State inspections. Same questions...unless YOUR state has a law specifically forbidding a CT on a bike, or requiring only MC tires, then a CT is allowed. Gut feelings and assumptions aren't legal grounds to disallow running a CT.
Next subject- those scared that CTs will suddenly be banned. Apparently you haven't thought this through very well. There are legal steps that must happen before laws are changed.
-Someone has to propose a change, and the first questions asked will be Why? Is there a safety risk? Give examples of accidents or injuries. So far I haven't heard of a single accident that can be blamed on running a CT. If it manages to get past the first step (unlikely), most likely a costly study will be proposed. The question will be asked again- why should the state spend the time and money on a study? Has there been sufficient examples of accidents, injuries, etc. to warrant a study about the effects of running a CT on a bike? As you can see, unless there are suddenly lots of cases of CTs causing crashes, its unlikely they will ever be "banned". And if, for some strange reason a couple states DO manage to outlaw them, it won't affect everyone.
Funny thing though, we are such a small segment of the riding population that nobody cares. How many riders run car tires? A thousand? A couple thousand? Nobody is going to waste time investigating an average of 50 darkside riders per state. I think they have bigger things to worry about than people using car tires on bikes without having accidents- they don't even have helmet laws in all 50 states (not that I agree with them, just using an example), and that would save many lives.
Considering the odd, strange, and poor handling motorcycles that have been built through the years, I really doubt anybody of substance really cares about us running car tires. If anybody was really concerned with unsafe motorcycles, I think there are some other places they could start before getting to car tires on bikes.
