They are legal in the states where they are actually needed at times, rather than going with chains.
But agreed, for typical drivers, they aren't really needed.
Worse, many of the dealer installed studs have the bad habit of coming out of the socket at high speeds. Only the Nokian factory studs avoid this and have awe inspiring top speed ratings to my knowledge. The Nokians are quite noisy, worse than any others I've used, so buy em only if you really drive enough in horrific cold ice covered roads enough to benefit from the difference.
