I haven't had a puncture once ever since I got my 4 Seasons about a year ago and I often take really bad roads. I heard about Michelin Krylion Carbon tho.
What is the advantage of these tires compared to the 4 Season or even the Conti GP 4000s?
I have gp4000s on my carbon bike and use them for best and racing. They are great tyres, very grippy, but have less puncture protection than the 4 seasons but I didn't find the 4 seasons very much more resistant. Thorns seemed to happily work their way through.
They were fast enough and maybe ok on a winter club run bike but not hardy enough for the commute in my opinion.
This is all only my opinion.
I've done a few thousand miles on the Krylion carbons now - commuting miles and winter club runs... I also cycle past two tips on the way to work. Not had one puncture yet... Touch wood.
