My 2010 GT drives straight & smooth with no handling issues but it is scalloping the inside tread on the front tires. Other than toe adjustment I don't think there is camber or caster adjustments on these cars. Just wondering if others have had this problem and what the fix was if there is one. I rotate every 5000 miles and have 16000 on it now so all the tires have been on the front and all are scalloped. I now have the rumbling tire syndrome.
