yeap i had the same wear pattern on my aveo too. Until I replace the shocks and get a good alignment, I will continue that crappy wear. Rotating the tires helps and just slows down the pain of replacement.
Now regarding tire noise. I bought tires for the ranger and over time they developed a vibration at 35 and 70 mph. I had them looked at by serveral mechanics. And the all said, the tires were bad. Even spin balancing them did not help. So I just drive those speeds anymore.
