C6 Wheel Alignment
Noticed yesterday while under the car, the front left tire is badly worn on the inside tread. All other tires are in good shape. At 25K miles, New OEM Goodyear Eagle EMTs were installed. They have 10K miles on them - I don't know if the alignment was checked at the time. Is there anything unique to this car (C6 Z51 Roadster) that could cause this other than a simple alignment? I would think an alignment out so bad to have caused this would be visible. I have had no indication whatsoever that there was an issue, the car tracks very straight. Looks like a new set of tires and an alignment are due prematurely.

It IS the alignment, and it does have to be done, sometimes, more frequently than when you change tires. An alignment can go out on some cars (ours, too) with just a bad bump. It is preventive maintenance. From what I've been told, everything needs to be tightened very well, too.

I hope you had them take out much neg. camber as possible and to go near ) toe; if not, you are still in for trouble. Hopefully they got it right. Took us three sets of tires on my wife's GS!

You can go up to -1.0° camber just as long as you have near 0 toe. It's the combination of negative camber and non-zero toe which gives you the scuffing one the inside edges of the front tires.
Below are what both my Firehawk and Vette are aligned to and I don't have any abnormal tire wearing issues at all. I used Pfadt's recommendations as a guideline and the guy who aligned it does a lot of alignments for road course and autocross cars. There was a trailer-ed in road race prepped Viper ACR waiting to get aligned after me the last time I was there.
