Well there is the debate about the gravel and CX bikes but here,
essentially, all the roads, or at least all the roads I see, are

I think the narrowest tires ever used for more than a short time were
25mm. I've spent most of my road riding time on 28s, some on 32s, a bit
on 35s or 37s when doing loaded touring.

It seems the latest data indicates the super narrow tires have no lower
rolling resistance than similarly constructed wider tires, unless you're
on a surface as smooth as a velodrome track. And wider tires tend to be
less flat prone and more comfortable.

That is a too simple conclusion. I mentioned this earlier:
