good to know,
I sure wish the last set of Michelin tires I bought has been soaked in the stuff, antiozonante.
{It is called blooming. It is caused by the antiozonante that is in the tires to prevent cracking etc. I would not worry about it. You can probaly wash it off but it may come back.)
Those suckers started the old Michelin sidewall cracking number and the Michelin tire dealer told me he would not feel safe pulling my trailer during the hot summer time with those tires.
about half tread left.
but they sure drove good on a heavy old stiff chevy 3/4 ton truck.
so I got more tires, not Michelin.
