Anyone talked about this before? I am getting info that Cobalt had been added to tires originally to resist tire oxidation (dry rot) but recently has been found to increase "stickiness" in the colder temperatures, and manufacturers are using more just to create better traction in icy conditions.

My new Toyo's seem MUCH stickier than any past I have been on. Anyone with any more information on this?

Don't know but here's wikipedia on cobalt:Catalyst

[/URL] Cobalt and its compounds; especially cobalt carboxylates, known as cobalt soaps; are good oxidation catalysts. They are used in [URL="http://en.wikipedia.org/wiki/Paint"]paints (http://en.wikipedia.org/wiki/Cobalt#cite_note-WhyCo-10), varnishes (http://en.wikipedia.org/wiki/Varnish), and ink (http://en.wikipedia.org/wiki/Ink) as drying agents in which the oxidation of certain compounds leads to the drying.[11] (http://en.wikipedia.org/wiki/Cobalt#cite_note-WhyCo-10) The same carboxylates are used to improve the adhesion of the steel to rubber in Steel-belted radial tires (http://en.wikipedia.org/wiki/Tire).[11] (http://en.wikipedia.org/wiki/Cobalt#cite_note-WhyCo-10)
