I haven't tried the supersport yet.
They are my next choice as I will be getting them for my balled out tires.
The last Perfromance tires I had was some kind of nitto's, I forget.
Before that was kumho's, i forget what the full name was but that thing hydroplanes.
And the one before that was Falken's, i'm not sure what model, I just remember seeing it on forums and car shops and so I got some, I was dissappointed.
But the one's I have right now, I can tell they are better becuase now I know how you can tell if you got grippy tires, it's when you drive out on a warm/hot day and you hear gravel kicking up on your car, that means they are gripping and sticking everything on the road and actually picking up the gravel up from the road. I can't recall what they are though as I don't have the car with me right now. They are Dunlops Direzza's something.
The one on the civic si are... Hiffy HF805? I never heard of them, but those things ride harsh and stiff and came with the car.
I'm slowly making my rounds with affordable summer/sport tires.
