I talked to another guy at another bike shop. He didn't think that going from a 32 to a 28 would make enough difference to be worth it. He didn't think I'd notice that much difference, even if the tire was a higher pressure tire.

He also said that with the smaller tire I would be more likely to have flats riding on the road (as opposed to the rails-to-trails bike path)

I was interested in Bontrager Race Lite Hardcase tires and no one had them locally. Of course I could order online but I'm wondering if I should just forget it.
