I've had a couple of Marathon Plus (25c for 6,000miles & 28c for nearly 10,000miles). In the last 8 years and 16,000miles, there are lots of cuts on the treads but ONLY ONE PUNCTURE (biggest thorn I ever seen after one of the storms in early 2024).
I now changed to Durano Plus 28c. Same puncture protection technology as Marathon Plus but "road" tyre category. Just did 46miles on it yesterday. A bit harsh (same 70 psi), a bit thinner (actual width measured on D+ is 29mm and M+ was 32mm). But my word it feels and is FASTER (1.5mph) than Marathon Plus!
Too early to determine the puncture protection level on Durano Plus, though. Time will tell.
