I had my WRX for a year and a half, and the entirety of it spent on the stock Dunlop tires.
Above 50°F, go ham. Have fun. They're great.
Below 50°F, don't take high speed corners. If you normally go 40 around a corner, go 35 instead.
That being said, I never lost traction with them, even in 40°F rain. The only time they ever broke loose was when there was snow on the ground, which is expected.
