Looking to replace tires on my GXP. Any ideas?

Don't go with anything less than a 255 section width.

I love my Bridgestone Potenza'*.

Goodyear Eagle F1 All Season

Depends how much you want to spend...got a set of winter tires? I chose to go with a strictly summer tire on my GXPs, traction is great, I was doing 2.1 60fts at the track no problem with a basically stock SSEi.

Goodyear and Bridgestone are what I'd recommend, or if money is an issue go Yokohama or Dunlop.

Go with a 255/45R18 for a size

but to make a suggestion, yeah, you using these year round?

and also, you planning on getting them online or somewhere in Appleton/Kaukauna

*edit* assuming you're running them year round, I'd recommend

Michelin Pilot Sport A/*
or
Goodyear Eagle ResponsEdge

And in order of priority, I recommend the Goodyear over the Michelin.
