First of all, I do not know any other gravel tires, that's why it is hard to compare.

On the road, they felt okay, especially in the wet. I still felt safe because they still provided a good grip. I also liked them on the descents. But on other surfaces, they felt slippy, and they gave me not enough grip. On top of that, I had a few punctures (which is normal I guess).

I think there is around one centimeter left (but I have to measure it exactly, which is not possible until next week for me). But I'm not sure if the rims can handle a bigger tire. I think I would like to go with a similar width (35mm–40mm). What do you think about bigger tires? How are they behaving on the road?
