best tire for this bike

I have a trek 1000, what is the best tire for this bike, 700-23 or
700-25 and what tire has the best rolling resistance rating.

Your weight, riding style, terrain, weather, etc are all important
factors. For rolling resistance, given exactly the same tire at
exactly the same pressure where width is the only difference, the
wider tire will reduce rolling resistance.

You can google groups for an explanation, but long story short:
- Contact patch area is determined mainly by pressure and load
- the wider tire at the same pressure doesn't have to deform as
much to provide the same contact patch, so has less RR.

If you sometimes ride on rough roads, you will appreciate the comfort and
stability of 700 x 25. For a discussion of rolling resistance, see:
