I wouldn't worry about it. Some people had problems, but plenty of people didn't. My Goodyears had high mileage and perfectly normal wear when I changed them out for my V-reds. I only changed to V'reds because of price and a nicer ride than run flats. I have another local friend with plenty of miles on goodyears and no signs of problems. Just keep an eye on tire pressure and your alignment just like any other tire.
