I own 2007 Toyota Matrix. 28,161 current mileage. Four (4) good year tires - Eagle P205/55R/16 come with Matrix. Defective tires. Other 3 tires still looks good condition but one of the sidewall dried prematurely and the tire apart into 2 pieces while I was driving. I sent the email to contact Goodyear last sat 8/27/2011. For safety reason, I would like to change different model tires. But Goodyear did not reply at all. I take some pictures also.

1. we were driving down the highway at 60 mph and the car began shaking harder and harder. 2. the tire's sidewall was completely shredded on both sides, as if it were defective. 3. the tire will have to be replaced, but it is no longer under warranty as of last month.

Have a 2007 Toyota Matrix--was less than one year old and had approx 17000 miles. Notice the tire looked low on air one day--removed the tire to check for nails or damage and found no--so took the tire to a garage and they put the tire in a water bath and found a leak on the side wall--I tool the Goodyear Eagle tire to a good year dealer--as that was the original tire on the car--they would not replace the tire--so decided to buy a new set of michelins. When the Goodyear tire was removed from the rim the mechanic showed it to me and the bead on the side wall--about that is in the vicinity where the sidewall and tread are joined was severely cracked--he said it was a blow out waiting to happen and definite defective tire for less than a year old vehicle and only 17,000 miles.

Potential failure - execessive tire wear. I had the Toyota Matrix tires rotated at the dealership at 5,000 miles was never told that I had, what should have been very noticable wear to the service department. I had the tires rotated again at 21,000, and the mechanic said the tires had very execisive wear from a the front end being out of alinement. I am the only driver and a careful driver. I believe this car was out of alinement from the day I bought it, and the dealership should have alerted me of my 5,000 check up.
