I have a 2007 Impala, new off the lot. Yes, the rear wheels do lean in and wear tires pre-maturely. My daughter has a 2008 Impala, and her tires are also leaned in. Can this be fixed under warranty? Can a factory recall be initiated? Finally, do you have to have aclass action suit in order to get someone to admit a problem?

I had similar problem on my 2008 Impala but only on one rear tire. Turns out the strut was going bad. replaced all four struts and that fixed the problem.

Yes it was actualy very common for the 08 impalas.

have someone pull the wheel off and check the bearing. it is riding on the inside of the tire if it is worn there.

have u ever had an alingmant and do u have the tire rotated every 10000km? bith of these can contribute to pre mature tire wear!

Hi:
Usually the shop that does the alignment will check the status of all four wheels and tell you if they are in or out, before you pay. That was the case for me, when I had an alignment, when I bought new tires. My back tires were wearing ok, but the alignment was slightly off, so I had all four wheels lined up . The cost difference was slightly more than just a front alignment. If you are on a tight budget, then you could let the rear tire alignment go.

has anyone checked the alignment? this should have been done when the first set of tires were wearing irregularly and replaced.

Nick52284,
I have gone thru 3 sets of good tires now. Tires lasting from 10-12k miles before they hit cords. This is after the dealer does an alignment to spec. Funny thing is I have never seen the alignment specs from the dealer, I only get "aligned to spec". My wear is on the inside of the tires just as described in the police bulletin. I have tried different brands each time and get the same result (wear to the cords in 6 months or less). The bulletin only applies to the police version becasue GM doesn't want the bill for the thousands of ordinary customers repairs. There are enough complaints of this exact thing on any Chevy site that you can find. We aren't all nimrods.

You may be a guru, but I think you don't know what you are talking about.

this is a wheel camber (in and out tilt of wheel and tire) problem, u may have to have a Camber adjustment kit put in, most new cars have no adjustment provided for this. the bottom line here is you need to see a really good front end shop to get this taken care of, also the tires will continue to wear this way even if problem is corrected, so may want to replace them or rotate them.

REAR WHEEL ALIGNMENT
TOE-IN : 0±2 mm (0±0.08 in.)
1. The rear suspension lower arm mounting cam bolt should be turned an equal amount on both sides during adjustment. Right wheel : Clockwise direction : toe-in Left wheel : Clockwise direction : ton-out Maximum difference between LH and RH : 3mm 2. The cam bolt should be adjusted within a 90° range left or right from the center position. CAMBER Standard value : 0°±30´ Maximum difference between LH and RH : 3mm : 0±2 mm (0±0.08 in.) 1. The rear suspension upper arm mounting cam bolt should be turned an equal amount on both sides during adjustment. 2. Install the left and right springs which have the same identification color. 3. The cam bolt should be adjusted within a 90° range left and right from the center position. TIRE WEAR 1. Measure the tread depth of the tires. Tread depth of tire [Limit] : 1.6 mm (0.06 in.) 2. If the remaining tread depth is less than the limit, replace the tire. When the tread depth of the tire is reduced to 1.6 mm (0.06 in.) or less, the wear indicators will appear.
