I own a 2005 GT and I have worn out 4 tires on the right rear. Two were replaced by the dealer under warranty and each time I was told that the alignment was to spec. With my newest tire beginning to show the same wear pattern I took it to an independent alignment service. The owner told me that the spec for the G6 is for negative camber on the rear wheels with a slight toe-in. This would correspond to the wear pattern that I am experiencing.

Has anyone had a similar problem? I wonder if resetting the car to 0 degrees camber with an average load (slightly more than 1/2 tank of fuel) and no toe in will eliminate the problem.

Any suggestions would be appreciated.

how soon does the tire wear? if more than 7-10,000 miles pass then your not rotating your tires. have you been rotating every 5-7,000 miles? rotations should be done with every oil change or every other depending on how often you change your oil.

Still confused.

Tires have been rotated every 5,000 miles. The wear patter shows up before that time period. I still question the specification of negative camber and a toe-in condition on alignment.

If the alignments settings are wrong, then all the the G6 and Malibu's would have your same problem, they all have the same specs.
I ran a Malibu 44 K, never aligned, rotated about every 5-8 K and traded with factory tires still on.

It could possibly be a stubborn spring or shock absorber at that location. If the k-constant is not correct then it could be applying too much force to the tire regardless if it is aligned correctly. I believe it was too loose you would feel it. Check the spring and the shock and compare a load test to both the left and right rear suspension.

Take it to an alignment shop. They will tell you what the problem is . You can fix it yourself or have them fix it.
