I live in Indiana and drive all over the country (20-30k miles a year). I drive on just about every surface/condition as fast as possible (personal top speed 145mph in 2005 limited roadster), including some off-roading (seriously, you'd be surprised how well the Crossfire handles, It's been driven out in the middle of the desert and up on ski-trails).

I need tires that will hold-up to the abuse, handle well in the corners/wet/snow. Does such a thing exist?
