Wow, I have had really bad luck since switching to tubeless. Blaming luck and not the tyres at this stage because there is no way to tell how a trusty Gatorskin or my old GP4000's would have coped. My pair of Giant Gavia AC 1 (25mm) lasted about 1000/2500km (F / R) Giant Gavia AC2 (28mm) rear lasted 2500km. They all suffered cuts that just sprayed sealant everywhere. no slow death, just catastrophic failure. I did have one puncture that sealed without me knowing - other than that they have been a disaster. On the plus side, the 28's are plush, especially with lower pressure. They are heavy though... It's been an expensive trial and error process. Like I say above, not sure if it's luck or the tyre (Giant or tubeless itself) and there is no way of knowing how a different tyre would have coped. Not sure if I should try a different brand or switch back to ordinary tubed tyres (like GP5000 and Tubolito's).
