Americas Tire/Discount Tire. Same company.
I have Nitto 205/55 and got them there. They actually will get you anything you request. They come in a 195/55 also.
NT450 - Entry-Level All-Season Ultra High Performance Radial
If you want an ultra performance tire and have deep pockets the AO48 are excellent and they make a 60 series
