I got over 3500 miles on my rear GP4000S, then moved the front to the back, and put on a new front. No punctures. I've picked out tiny slivers of glass that didn't go through the protective belt. They seem to have a lot more grip on the corners than my old Michelin Krylions.
However, I've seen two other posts lately with
unexplained sidewall splits. Of course, there's a lot of forum readers using GP4000 tires, so who knows.
