In your opinion, what PSI rating are you looking for in a hybrid tire, for maximum speed on pavement (minimal riding on groomed gravel trails)? I'm looking at a Kenda K-198 700 35 rated for 50-85 PSI. Is that typical of a hybrid tire? Would you ever go thinner, to a 28?

I'm also trying to set my hybrid up for a more aggressive riding position (it is a city/cross bike) with longer stem (40mm to 90mm). I'm moving from a 660mm bar width to a 600mm. Do you feel that will give me more speed?
