I've owned a set of Eagle HP's in the past and found that while they provided fairly good grip, they were also very loud.
On the ZX2 we have a set of GS-C's. They suck. On dry pavement the car squirms left and right with torque steer, it drifts through corners at only moderate speed and they transmit tons of road noise.
For the Contour, we ride on Kumho tyres for the winter (732 touring) and find them to be excellent. Very little noise, excellent grip, good fuel economy. In the summer we ride on BFG Comp T/A's and they are quite simply the best tyre we've ever driven on. I've never even heard a chirp from these in the corners, no matter how hard I push. These tyres are simply the best!
When Goodyear makes something that compares to the T/A IMO, I'll buy a set. But they'll also have to be priced the same. Given the poor performance of the ZX2's tyres, I don't see much to look forward to.
On a side note, I had to replace by rear winter tyres on the Contour soon after buying it. Since the 732's weren't available locally I bought a set of Goodyears (can't recall model). Since then, I've noticed the rear end of the 'tour likes to slide around a lot more. It did not have this problem with the original Kumho's.
