Also the standard PP has a hard compond all around, were as the P2CTs
have that same hard compond in the center and a more softer compond on
the sides. Depending on how you ride, if you do a lot of twistys P2CTs
will give you the most grip on the sides, and wear more out on the sides, but wear less in the center.
If you ride on and off I stick with the standard PP, they handle the
same but will wear evenly all around longer or only on the contact
points you use most. Why spend more if you use the sides of the tire less and
wear down the center for the P2CTs. I hope I made sence.
