I’ve used 35c Vittoria Hyper Voyagers, fast and comfortable but do slip in mud. Ran with tubes, never had a puncture.
Then Gravel King So in 35c. Initially I was disappointed at the perceived increase in rolling resistance, but didn’t notice it after the 1st ride. Better grip where the Vittoria’s slipped, I think they’re a great all rounder. Ran tubeless, did puncture but it was a piece of glass that most probably would have punctured the Vittoria’s if I was riding on them.
Now running Gravel King slick 28c with tubes. They’re fast and comfy on the road, I’d consider the larger sizes for gravel too. The gravel/light off road I use mine on is a mix of surfaced and hard packed dirt tracks. The SKs come into their own on hard packed dirt after a bit of rain as they seem to have just enough bite to hold on.
