They are supposed to be "Rain Tires" but they seem more like SNOW TIRES!
They have 2 big zig zag treads in the middle where you reside when riding straight down the highway. There is actually a height difference between the jagged outer ends of the zig zag pattern and the rest of the tire. Every time you start to lean into a turn you get about 12 degrees into your lean and it feels like you have bumpy training wheels on your bike. I looked into it and found it was not just me... see pasted quote and link below. I am heading on a ride from Seattle to SF labor Day weekend and tried to get Avon Road Riders which people from my shop use and swear by. Of course they will not be here in time. I finally just went out there and SANDED THOSE BUGGERS OFF!!!!!!!!
I put it on center stand, let the wheel spin in 1st 1500rpm, and used a soft sanding pad with some 40 grit sand paper and ground those points down so that the whole profile is round. NEW BIKE!!!!!!!!!!!! unreal..... corners VERY well now. NIGHT AND DAY! if you want to try it, only sand down those 2 points just off those 2 big center strips. You can feel the bumps with your hand quite easily. Hope this helps.

"The rear isn't quite as impressive; it isn't breaking in as quickly. And I'm not sold on the 3 circumferential grooves, which live right at the contact patch. They seem to cause the tire to want to track straight, so when the bike is first leaned into a corner, the rear feels a bit like it's stepping out until the bike takes a set. This is exacerbated by the typical "rubber cow", hinged-in-the-middle Airhead suspension feel.
