Front is still on and over 7,000km
Rear did 5,000km ish.
The bike was used before I got it on a media trip, so will be a little higher, but not much.So year, they wear well.
The tubless ones are anything but fragile. I commuted 90km across london, I pulled glass and all sorts out of them, yeah they had cuts, but all sealed on the own. Eventylly I got a big tear on a nail, but I plugged it. I replaced them not long after as they were getting well worn.
I am runnign some wtb exposure on the back now, they seem just as durable. Not sure on RR.
Not ridden them myself but considering them at the moment. Just spoke to the mechanic at my LBS and he reckons that GP5000 TL (tubeless) are better than standard GP5000s - thicker and puncture less. GP5000 TL > GP 4000, but standard GP5000 < GP4000, according to him.
I'm not sure anyone is finding that GP5000s wear out fast, @skinny said this recently:
