Experience vibration between 40 and 70 mph, feels as though tires are skipping on road surface. Driver input is limited by the response of tires. All 5 tires were replaced, experiencing same condition again at 4,000 miles. Have returned to dealer regarding same problem, and am going tor return once more as problem was not corrected. My father has a 2001 GMC Sierra with the same problem, same size and model tires have been replaced 2 times, awaits third replacement. Coworker has 2002 Silverado, same tires same problem. Both additional vehicles have under 5,000 miles. (tiresize: 255/70/R16)

We are experiencing exessive trembling of the steering wheel and shaking of both outside mirrors. Truck has been taken to 3 different dealerships with no solution to the problems. The last dealership near our home has replaced both front tires, and during our last visit (12/03/01) they replaced all 4 tires!! please help, as we are afraid to drive the truck with our 2 kids in the back seat!!

Both front tires are wearing and dealer says there is nothing wrong, and will not repair front end.

The tire size is LT245/75R16. There wasn't enough room to fit it all in the space provided. After changing the tire, I found that a lug in the tread was torn from the tire with a one inch tear. It was not a straight line, and it followed the Contour of the side of the lug. This told me that nothing punctured the tire. I haven't contacted Firestone yet. I have the tire and don't want to give it up. I have been displeased with having these tires on my truck, but the dealer wouldn't replace them. Now I've had a failure and I know you have been investigating these tires, and I want to add my name to the list of people with problems, with the hope that I can get all five of my tires replaced. I also am hoping that something can be done that will keep people from getting hurt by these tires. Thank you for your time. David C. bray. (dot number: Vn11bad160 tiresize: Lt24575R16)
