Snoking you obviously know more than I do about tires. I believe it is a safety issue and there should be government intervention. Rubber flying all over the highway especially if it is Interstate could cause a fatal accident. One of my ST tire failures was on I-75 3 lane in that section and was as close as you can come without a smash up. I hope the people needing tires are now informed and will not buy ST tires and save themselves from being involved in a serious or fatal accident. Was glad to see your post, maybe those that doubted will accept what you are saying. I found that some dealers won't sell anything except ST tires for a trailer saying they are made special for trailers. Truth is they are made to fail to bring you back for more tires. It is a Tire Industry Scam and that is why I say ST stands for SCAM TIRE. REGARDS
