I purchased a used 2008 Chevrolet on 10/15/2010 and the dealership put a current inspection certificate on the vehicle. During an unrelated visit to my auto mechanic he noticed the tires ( front only ) and stated they were not good and if he would have inspected the vehicle, he would have placed a "rejection sticker" on the M/V. I took the vehicle to the dealership who stated they were ok. Went back to auto mechanic who advised me to file complaint.

The contact owns a 2008 Chevrolet Impala. The contact stated that the tires were wearing prematurely. The front tires were replaced by an authorized dealer at 5,000 miles and again at 18,000 miles. The recommended tire pressure was 30 but the dealer recommended 35, which the contact believed was a safety hazard because it was outside of the original manufacturer's recommendations. The manufacturer offered no assistance when contacted. The vehicle was not repaired. The failure mileage was approximately 5,000 and the current mileage was approximately 19,000.

Purchased new 2008 Chevy Impala only to have excessive tire wear front and back at 13,000 miles when car was 1 1/2 year old. I needed to purchase new tires at that time. Today I learned I need to purchase another set of tires at 26,500 miles. Have had tires rotated regularly and aligned. I thought the first set of tires from the dealership were just "cheap" tires so when I replaced I replaced with good tires. Still need a set of tires A6 13,000-14,000 miles. This is a disgrace. I am just beginning the process of having this problem corrected (I hope). GM did put bulletin # 08032 for police cars regarding this issue. I guess john Q public though is not as important as the police.

Sidewalls on all the tires were wearing down abnormally!!! 19,000 miles and I need to buy 4 new tires!!!

- Neenah, WI, USA

Noticed abnormal and excessive tire feathering. Had researched and found previous to my own experience that others had the same problem, so I had been monitoring my own tires to see if it was a design flaw. One mechanic told me after I purchase 4 new tires, which only have 34,000 miles on a 50,000 mile rating, he would try an alignment to see if it need four new struts as he was assuming was the main problem behind the tire wear. I called a local GM service center to see if they had suggestions for me. The guy told me 4 new tires and the few others we have serviced with the same problem, an adjustment had to be made by elongating the holes to pull the tires into a good alignment, eliminating the outward camber. He found this info in a technical service bulletin. GM has recalled public service vehicles, ie police cars, of the same make and model, but has yet to see the public safety hazard behind this easily remedied issue. I was told it would cost me at-least $700 for prematurely worn tires and repairs and adjustments. Imagine if I had been aware of this previous to my own incident. I would assume I still had 15-20000 miles of tread-life left and would be driving my car as if there were no problem at-all until my tires blew while driving my son back to his mothers house, causing an accident, killing my son and I as well as two others in another vehicle. There-in lays the safety issue. A prompt and thorough investigation will show it's a design flaw that is putting lives at risk. The sooner the defect is corrected, the sooner peoples lives and wallets can rest at ease. I would certainly be willing to answer any other questions regarding this issue.

Severe inner tire wear on both rear tires at around 47K miles. The wire inside the tires was showing and it was unnoticeable just looking at the car. I didn't realize the tires were bad until the rear driver tire went completely flat without warning.

I have a 2008 Chevrolet Impala that has 40,000 miles on the vehicle. I will now be putting a 3rd set of tires on the car as well as getting the front end aligned once again. The car wears the tires on the front inner and outer sides. The middle of the tire looks new. The car handles horribly in wet conditions as well.

2008 Impala ltz that I purchased from bill cramer motors in donalsonville, Georgia on 10/29/2009. On 2/6/2010 I had a tire blow out in bainbridge, Georgia nearly causing a crash. After changing my tire, and returning home I discovered that both rear tires were worn down to the belt on the inside. After doing some research on this issue, I discovered that this is a very common issue in the late model Impala's. I called the shop today (2/8/2010), and they advised me that they are unaware of this issue. I also called solomon Chevrolet in dothan, Alabama (1-866-646-6175). They advised me that they are very familiar with this issue, and that it needed a rear camber bolt kit and a realignment to fix this issue. The parts and labor for the kit were estimated @ $200 and the alignment @ $70. I would also like to note that my car is still under the 12,000 mile certified warranty. My car had 34,861 mile on it when I purchased it, and now it only has 45,690 miles on it. So I have put a total of 10,829 miles on it. The tires that are on my car were brand new when I purchased it. There is no way possible that I should have to be replacing 2 worn out tires within 10,829 miles'. this is unheard of'

Started having issues with my 2008 Chevy Impala with what I thought was a tire balance problem. Did required tire rotation as recommended at 6000, 10,000 and then again at 13,500. Dealer said tires may be out of round and suggested road force balancing at 16,500 miles. This did not change the issue, so went to Goodyear dealer and found out that the inside 2 inches of all four tires were wearing excessively with the rear two less that 2/32 inches of tread left. Goodyear shot the alignment and showed that the alignment was way off and tires could not be warranted with an alignment issue. Took back to Chevy dealer to inform them of the alignment issue. They said alignment was not warranted after 7,500 miles and also would not replace the 4 tires. I did get the dealer to gratuitously do a 4 wheel alignment that also showed the camber and toe, especially in the rear was "out of tolerance and exceeded cross-tolerance" on their machine as well. The camber could not be adjusted without extra work (elongating the bolt holes or a chamber alignment kit). Contacted GM complaint line for resolution to no avail, saying I had to prove that there is a defect on the vehicle. This is an inherent safety problem with 2007 and 2008 Impala that has fostered numerous complaint to you including 5 already this year. GM issued a tsb #08032 for police Impala that are on the same platform and suspension, but never extended that to the public. Seems to me that the rear suspension has an severe defect that can cause tire blowout without warning. No tires should wear like that with less than 17,000 miles without a rear suspension and alignment problem that needs to be recalled for repair and replacement of the parts and tires. I saw at least 12 complaints in the first 24 pages of 2007 Impala complaints to the ODI. Please investigate this problem before someone is seriously injured or killed as a result of this continuing Impala issue.

Extreme inside rear tire wear in a very short time.

- Flushing, MI, USA

Rear tires had extreme excessive wear on inside in short amount of time. These were new tires. No warnings. Tire was worn in such a short amount of time if I had not been looking at something in driveway it was on the verge of a blowout. These were new tires so you do not think the inside where you can not see would be down to the wires on the inside of tire. Was going on long trip in 2 days something just made me look down and I saw it. I could not believe it. I took pictures.
