The GP4000s uses BlackChili compound while only the BLACK GP4000 has it (The coloured GP4000 use ASC - which is a silica compound). Also the graphics are different.
We've sold a few thousand of these tires without a single problem. I've been on them for over a year and they have been completely reliable and roll very well.
