50mm bike tire recommendations

Hey everyone,

I’m currently running Schwalbe G-One Bite 40mm and I’m thinking about moving up to 50mm for a bit more confidence off-road. Where I ride it’s not groomed gravel or proper official well-kept MTB trails, just typical unmaintained forest trails: holes, roots, loose rocks everywhere, some of them golf-ball sized. On descents, it feels pretty sketchy with the 40s.

The problem is, I don’t have long stretches of continuous/unbroken nature. It’s more like short nature pockets in between civilization so, I still need to transverse a few roads (tarmac and cobbles). So I’m trying to find something that’s still reasonably fast rolling on road. I was hoping to find something up to 20 watts of rolling resistance. I think I saw somewhere that my tires are around 25 watts, so some improvement in this area would also be nice.

I started investigating tires on bicyclerollingresistance.com website and started looking at measured knob height (center and edge), trying to pick something with more bite than what I have now. But the more I read, the more I see people saying knob height alone doesn’t mean much and tread pattern matters more. At this point I’m not even sure what I should be looking for.

These are the ones I’ve selected for the moment:

Schwalbe G-One R Pro 50

Schwalbe G-One RX Pro 50

Schwalbe G-One Overland Super Ground SpeedGrip 50

Alternatives slightly above 20 watts:

Continental Race King Performance ShieldWall 50

Pirelli Gravel M (tested in 45mm, but there’s a 50mm version too; hopefully they perform similarly)

Maybe other brands or models I should be considering that aren’t on BRR?

But honestly… I don’t really know what I’m doing. I started by filtering by wattage and knob height, but it seems the tread design or compounds are even more important.

So, in conclusion, what I’m after is:

More confidence on rough, loose forest descents (I'm not doing jumps. Let's say, more like XC)

50mm volume

Still decent on road sections

Not feeling like I’m dragging an anchor on pavement

If anyone has experience with these in real, messy forest conditions (not nice smooth gravel), I’d appreciate some advice and recommendations. What should I actually be looking at when choosing?

Thanks in advance!
