No such thing as "GOOD" cheap tires! You can have the best suspension, but it's garbage if you don't spend where it matters most, where the rubber meets the road! Don't skimp! : )
ive vey run the Portenza's for a while now and love em', but I don't get 40k out of them... I have agressive alignment and drive aggressively as well. That said, I've never lost grip, dry or wet. Snow... Eeehhhhh... they're So so...
