So I'm slowly bringing my $400 2005 CTS back to life and I find myself enjoying it. The previous owner just had new tires installed at Discount Tire in January, and they only have 1k miles or so. However, they're some off brand Radar Dimax AS-8 tires made in Thailand. I'm normally not a fan of cheaping out on tires and stick with name brands. The main issue is the size that was installed is 205/60R16, but the car originally came with 225/55/R16. They're almost identical in diameter so the speedometer is right, but they look so skinny. Am I losing out on a lot of handling/stability with this narrower tire? I spoke to Discount Tire and they said I could trade them in for a total credit of $100.
