I have a 2009 Silverado crew cab that came with Goodyear Eagle ls-2 tires--dot M62A bcer. Also, my Silverado came with a tire monitoring system. On 1 May 2010 I was driving in a residential area of wylie, Texas, very slowly, probably around 5 mph because there were cars parked on both sides of the street and people standing by their vehicles talking. Immediately after passing between the cars the rear driver's side back tire collapsed, apparently a blowout. I called my insurance roadside assistance that changed my tires. I asked the man who changed my tires if he had a compressor on his tow truck, and he did. Because he or I neither one could see any nails nor anything else protruding into the tire, I asked him to air the tire up. He aired the tire up and immediately said here is your problem'air blowing out of the side of the tire. I looked the road over where the tired collapsed, but found nothing. Twenty minutes earlier I was traveling on U.S. 75 in plano, Texas going 60 mph in heavy traffic. My Silverado will let me know if my tires are low. I had no warning before there was an apparent blowout. The tire had 27,700 miles, plus or minus a couple of miles, at the time it collapsed. The tire had good thread and had been routinely rotated. The tire monitoring system let me know when I put the spare on that I should check the tire. I have notified Goodyear of this incident.
