I think you mean "Poindexter", but I digress.....
It's a joke, homeslice. Go look at the quality of threads posted on sites like
www.gixxer.com. Historically, it's been 98% "wHaT kInDa tIrEs aRe dA BeSt?" or "wHeRe cAn i bUy rIm tApE?" The fact that you are asking about the maximum level of grip available for a tire to be used for canyon carving, puts in in that category IMO.
You're going to do you, but just realize that reckless street riding is typically looked down upon on this site. That's why most users are suggesting a Sport Touring tire like the Pilot Roads instead of essentially a cut slick like the Pirelli SC3, Power Cups, etc.... The limits of a DOT slick should be reserved for controlled environments, not Redwood Road.
