Tire Blowout problems of the 1997 Mercury Sable

I purchased 8 of these exact tires. 4 for my 1994 Ford turuas amd 4 for my Mercury Sable. Previosly on my 1994 three of the original 4 tires I purchased had to be replaced. All within a months time all at around 20,000 miles. The first tire blew the right front tire blew out when my wife was driving the car. A week or so later I noted that the tread was seperating form the left from tire. I contacted michelin regarding this and they said it was the way my wife was driving the car. Upon inspection the michelin dealer found a nother tire that was doing the same thing and they replaced them both at no chage to us. Last week I noticed that on my Sable the left front tire side wall was peeling the same as the others had done on my 1994 Ford. I notifed michelin this time they informed me to go directly to the dealer. They were not willing to replace this tire although it had the same deffects as the other two that where replaced earlier this year. At or around 20,000 miles the side walls of tires begins to crack and the tread begins to peal away form the side. It has happen to two different cars that I own. The same tire, two different drivers yet the same defect. I am not convienced that I am the only one having problems with these tires. I have purchased 8 of the same tires and 4 of the 8 have gone bad. Three tires showed the same tipe of defect. Please look into this as others maybe unaware of the danger these michelin symmetry tires. Thank you for your time.
