I recently mounted some 45 mm Pirelli Gravel RH tires on my Vado SL. It made a very noticeable difference in ride quality, which I would describe as more supple and compliant over bumps. They did change the handling dynamics a bit, so I needed some practice to become confident again during cornering. They tend to pull in the direction you're turning, so you must learn to expect that. It's different than the stock Pathfinders which had mostly neutral handling.
The verdict is still out on whether they have better cornering grip than the Pathfinders, but I think they're pretty close. I ride on mostly hardpack crushed limestone over dirt, so I figured I'd give these a try. They really don't do well in anything wet, such as a little bit of mud. I had a few close calls with them when cornering and hitting a patch of wet stuff. If I were to do it again, I'd probably just get the regular Gravel H tires or even consider the M's. I think I just need a little more tread depth than these RH's have. The Tracers posted above look like they might work well and also the Rhombus.
When I decided to get them, I was trying to find a wider tire with less rolling resistance which would give me more speed and these seem to deliver.
Yesterday I went for a ride and it was VERY windy, as in a steady 23 mph wind with 32 mph gusts. It was the kind of wind where if it's in your face, you don't need to use the brakes to stop. I used Turbo mode on the Vado for a bit, which is rare, to fight the wind. Then, when I had the wind at my back, I turned the motor off and was doing almost 30 mph without even trying. Thankfully, the tires managed to hang on in the corners, but I had a death grip on the handlebars.
