Only negative I've heard is that they are a softer tire, lucky to get 35-40K out of them. But that's just what I've heard, could be some mis-information too.
I'm at 32k have approx 30-40% left, holding up well but have recently noticed a lack of grip on wet pavement from the rears. Been good about rotating them. I like the boxy look they have on 22s. I swapped out the stocks and cut over to Black Rhino wheels when I got them, will redo once they are toast.
