JINKSTER said it Best.......I guess I might as well chime in here by saying....the rumors about Pilot Powers "Being Squirmy" is utter BS..but here's the deal...the GP derived rubber compound is 6% softer than any other make of tire in it's class hence it's absolute awesome levels of traction which btw include a "Wet Rating" of "5" (the highest wet performance rating michelin offers) along with a stunning "Lean Angle Traction Rating" of "50deg. dry/41.9deg wet"....and now here's the skinny on the squirmy rumors...
Because the Pilot Powers are made of such a soft (yet durable) compound?...they do like their psi....as a matter of fact they DEMAND it...and if you strat playing "The Soft Air Pressure For Better Traction" game they will become squirmy feeling as now you are running both light air pressure and a super soft compound....not good...and they'll letcha know when your air pressure is a tad low and do so right away...with...a squirmy feeling.....due to the combination of both light air pressure and super soft compound...however..I've found that if you keep the rear in the 40-42psi range and the front in the 39-41psi range?...you'll find you get great feed-back and levels of confidence you've never had in any other street going tires you ever rolled on....cause they stick to the road like a freaking electromagnet at just about any lean angle any immortal has the nads to hit.
But run anything less than 38psi in the rear and 36psi in the front and it's....welcome to squirm city....and that's where the rumors come from...guys who don't check and/or purposfully run....low air pressure.....thinking it's giving them better traction....such as at "track days"...but keep the AP right and tight?...and you'll be taking corners like something out of toon town...with confidence and more traction at greater lean angles than your mind will be willing to accept.
