OK, as some of those on the forum know, I retired from Michelin last year. The plant I was employed made the various rubber grades that went into tires in the US, and some overseas. That rubber went to the tire manufacturing plants. I hear a lot on this forum about tires cracking, etc. In the ?old days?, there was a termite prevention chemical I think was chloradane, and it?s effective life was about 30 years or more. The new termite stuff is effective for maybe 5 years, if that. The changes were for environmental reasons.
Tire companies trying to comply with environmental regulations in the US are constantly trying to find different recipes that are as effective, but still environmentally friendly. Foreign countries may or may not have the same regulations, and domestic tire manufacturers may or may not be as aggressive at implementing environmental standards.
Not trying to defend Michelin or any other brand, but I personally think sometimes when they make a recipe change it?s hard to predict the long term impact on the product, even though they do extensive pre-market testing.
