I am the original owner of a 2001 cetera. My car now has 42,000 miles. At approximately 22000 miles, having rotated the tires faithfully every 3000 miles, I went to a tire dealer to have them rotated, and was told not to drive on them anymore as the edges were totally worn out, exposing the canvas. I had been told all along that they were wearing unevenly, but chalked it up to the original tires, sometimes not being as good as they should be. Replaced with original, very expensive tires. Now at 42,000 miles, having faithfully rotated every 2 to 3000 miles, I am told that they need replacement again, having been told at every rotation that they were wearing unevenly every mile that I drive, I felt as if I was leaving money on the pavement. The dealer said that it' was the tires themselves, $160 each, and became very irritated and indignant when I told him that the tire dealer said that every one of the Cateras ate tires. One of the service advisors at the dealership told me that it was a problem on Cateras, but the service manager quickly jumped in and told me again that it was the tires themselves and not the car. He was very unhappy that one of his employees told me the truth. Now that I saw that others were having the same problems, just as the tire dealer had told me, I was very irritated that the car dealership has been covering it up all of this time. I spoke to GM headquarters, but they also denied knowing anything about there being a design defect.

The design of the front wheels was causing premature wear of the tires because the tires came in contact with the road at an angle while driving. Based from invoice from dealer, the front wheels of the Catera are designed to pitched slightly inward, which may cause the front tires to wear faster. Also, it was recommended that tires have to be rotated regularly.
