FWIW - I have ridden a couple thousand miles each on Gatorskins and GP4000ās on the same roads in an urban and suburban setting over a couple years. While the Gatorskins are more robust in the sidewall, the fact is the the marginal difference in the actual number of puncture flats is very small on the roads I ride on. Granted, we have a bottle deposit law so glass in the road is pretty uncommon, there are no native thorns or goatheads here and most of the streets I ride on are pretty clean. Iāve ditched the gatorskins and just ride 4000s and flats are pretty rare. Frankly I notice no difference in flats in my environment.
Gatorskins are tough and if you are riding in rough environments the drag is worth it. But for ānormalā roads, there really is little point suffering with Gatorskins when the 4000ās are almost as puncture resistant and way faster, and they feel better too.
