They are great tires, don't get me wrong, but time lost changing a flat is more than time lost by using the standard GP4000 v. GP4000S.
Your results are the exact opposite what me and all of my riding buddies have experienced. The GP4000 in black chili is the exact same tire as the GP4000S except slightly different graphics so if you've experienced differences on all black tires then it's just a coincidence. The other color GP4000 tires are much inferior due to the fact that they use a different rubber compound that doesn't hold up as well nor ride the same. The colored GP4000 tires we've used suffered many more cuts and didn't last as long as the GP4000S. WE used these for several years on multiple bikes so our sample size was large. Plus the road feel of the black chili crubber compound is much improved from the colored versions. We're experiencing 500-1000 miles longer life with the GP4000S vs the colored GP4000 on single bikes.
