I wore out some Goodyears in about 10,000 miles. The ones you had probably had a defect of being left too long in the vulcanizer and they put too much steel in them by accident. Amazing story, as few tires I ever had made in America lasted more than 35,000 miles. I used every type of European tire as well as Goodyears, Firestones, and a few other US brands. The Pirellis lasted 13 years. Michelin has a harder noiser ride but lasts very well. About three times better than Firestone, which is better than Goodyear by 50%. Pirelli was the world's best tire for 50 years, but has languished in quality lately. Continental is the widest used European tire and has very good quality. If what you say is generally true for that class of tire, then it has much to do with the car and the type of tire, rotation and the way it is driven. If you don't rotate US tires every 10,000 miles they will wear very quickly with some high torque drives, as the rubber is softer. If you don't pay very careful attention to inflation, then sidewalls will quickly self destruct. US tires are not as well vulcanized and until the advent of radial tire design, they would fail in sidewalls unless very heavily made with steel belts. The heavier tire worked against itself unless well inflated often. The radial could bend more in corners so its sidewall lasted much longer. In hard cornering on city streets the conventional US tire lasts not near as long as a radial. Until US manufacturers learned to build radials and suspensions changed to accommodate the tire, US radials were not good quality. A larger tire has to be built completely differently and for the suspension of type, as well as the suspension built for the tire and its tendency to roll in cornering. This was a challenge for US manufacturers as their cars were larger and unsprung weight ratios were greater. The design of the vehicle did not allow for a "rolling" or folding of the tire in a corner. The European tire has less of a sidewall and more of a "universal surface" so to speak. If US tires have improved significantly to counteract the obvious European advantage of the 70'sand 80's, I am not surprised, but a car that was driven hard in the 1970's with conventional belted non radial tires would have destruction of that rubber well within 30,000 miles. Not so their lighter and differently designed European cousins. EC<:-}
