I don't know how to rate Bergey's Chevrolet in PA for this, but they told me that the ONLY tires available for my 2LT RS are the P Zeros they came with.
I asked them about all-season replacements, just out of curiosity. I wasn't really planning to buy from them, because I thought it would be too expensive. I did not expect them to not have an alternative. They wouldn't even acknowledge that they were 'summer tires.'
Otherwise, they were fine. They fixed a squeak in my windshield that started happening when it got cold. They've changed my oil successfully.
