Tire Tread/belt problems of the 1997 Mitsubishi Eclipse

Front left tire continuously deflating, leading to rapid deflation because of a seven inch cut along the seam of the tire. Fortunately it happened at a very low speed and I was able to get off the road safely. I had just left the highway and was driving 70 mph. Replaced all four tires.

While traveling on highway front left tire tread separated from tire. Then a couple later, front right tire blewout. General, grabber (aw), p27560r17. Dealership is aware of problem.
