I rode 25c Conti GP4 Seasons for nearly 1200 miles without a single puncture but after that they became a bit unreliable and I wasn’t imressed with the durability of the sidewalks as already mentioned. The ride was superb though, lovely tyres.
I now been on 28c Durano Plus for the last 400 miles, yes they are rigid, heavier and they have definitely killed the quality of the ride but I’m confident in their durability and expect them to last longer than their predecessors, and I hope to have a problem free winter with my 5am commutes on dark country roads
