2008 Impala SS with 60 K on it. Currently have near bald Eagle Gt's. I purchased the car with about 54 K on it so I haven't experienced what a fresh set feels like. I have compared them to the Michelin Pilot A/S, . Set of Gt's with install around 800, the Michelins around 1000. Recommendations guys? Or do I need to look to a different set all together? I want to stay all season.
