I don’t think you can go wrong with G-Ones for the sort of riding you’re talking about. They’re proper quick on the road, acceptably grippy off road on anything bar mud and wet grass and are reasonably robust with it. Work brilliantly in tubeless mode too. The only thing wrong with them is that you have to shop around to find them at non-extortionate prices.
I sometimes use one out back with a WTB Cross Boss up front for more grip when it’s wet and slidey and that works pretty well too. I’m on the G-One all-round 35s, but the G-One Speed 30, which Ive also used, is also more capable than you’d think on gravel-type off road, just less volume and not quite as much grip on rougher stuff.
I’m sure there are other perfectly acceptable alternatives, but if you can find them at a reasonable price, G-Ones really are as good as the reviews say ime.
