tire dust is specifaly toxic to juvinile fish, and as all roads are ditched, any extream early spring rain event will gather and float a concentrated pulse of tire dust into the equatic environment and cause mass mortality in stream and river bound juvinele fish such as salmon my understanding is that it is additives used to make tires tougher that is the main culprit, so the anouncement of an essentialy zero cost way to gain longer lasting tires that produce less, less toxic dust is good news
