I drive the Hardy often and realize that the road is slightly "grooved" perpendicular to the direction of travel. It's slight to the point that I don't even notice unless in stopped traffic. I've ridden on surfaces like this before and some can be pretty aggressive to the point that it's rough like chip seal. I was wondering if it's "rough" enough that it's worth dropping 5 psi or so. Or is it pretty mild and not that big of a deal. I'm on 23mm GP4ksII with latex tubes that I typically run at 90 psi.
