35mm too big for meI have Continental GP4000S-2’s on my Giant Defy, I found them prone to picking up small splits which I ended up supergluing, my Marin Gestalt came with Schwalbe G-One Speeds, I had one slow puncture (Thorn) and found them to be fast rolling and grippy, the dotted tread pattern Only just started to wear on the rear after about 800 miles, I would say I prefer them to the continentals as they will cope with light off road too
28mm ?I'm on my third set of GP5000s. The first set did +/-6000 miles without any punctures but plenty of self-sealed nicks.
I did have to replace the second set inside two months but this was because both suffered tyre wrecking punctures - no tyre is going to survive a deep split 0.5cm long. I was very unlikely to have two of these in ten days.
Third set have been fine for the 1500+ miles I've ridden them.
