What Tyre Pressure Should You Use for Bicycle Touring? - CyclingAbout
Would 80 psi be the fastest? given 99% of my route will be sealed roads.
Would I risk any pinch flats at 60psi?
Why not just adjust tire pressure to suit conditions while under way? I never really got why people fixate so much on a specific pressure ahead of time rather than actually riding their bike and getting a feel for what is more/less ideal for different terrain.

There are sidewalks in places you wouldn't expect, way out in the country. The sidewalks have a very big curb and big dips at driveways, plus there are some hard core grasses that mess with them a bit.
The cops will yell at you to get on the sidewalk in places. IMHO having narrow tires isn't that big a deal though, my road bike with 23mm tires does just fine. It's a little squirrelly when there's sand/gravel but nothing that would make me freak out, even on those mountain roads that clearly haven't been maintained in years.
