Looks like they stopped it now, it was just a general sale on their website for easter.
Mind if I ask about your reasoning? I'm breaking traction midway in 2nd and into 3rd in some scenarios, and it'd be nice to have more lateral grip than all seasons. The car rarely sees rain, but I'd like to have a moderate amount of confidence in wet weather. AX people seem to like the 615 as a rain tire, and being a 200tw I assume they're at least fairly sticky in the dry as well. I'm a little worried about flat spotting over the winter, but I'm kind of hoping to get a second set of cheap wheels to just sit the car on over the winter.
