general problems of the 2001 Chevrolet Impala

I bought 4 douglas touring tires for my 2001 Impala on11/03/05 about 13,000 miles later my right front tire started to thump and shake. I had it checked. It was a seperated belt. I had it replaced and the tires rotated new on the back old on the front a month later the right front tire did the same thing. I had it replaced, this time I was forced to pay a 54. 00 pro rate. What happened to the wareentee of the life of the tire? now today the left front tire is doing the same thing. I can't affored to buy another one or two as the case may be. . . Help.

The consumer had noticed a thumping noise in the tires. The two rear tires were out of round and needed to be replaced. Between the dates of April 17th and August 22nd 2002, the consumer stated that the vehicle developed a new thumping noise, was later told that the tire is out of round, goodyear tires.

When driving vehicle would make a thumping noise. Took vehicle to dealership, and had tires replaced. Problem was getting worse. Took back to dealership, and mechanic indicated that aluminum wheels should be replaced with steel wheels. Had been to dealer 5 times for problem.
