Sorta related to this thread... I got my first flat in my Forte Metro's (1.5" / 65 psi / $7 ea). Would prolly go the rest of the season, but would rather replace than get flats because of thin tires.. The store didn't have the same thing but did have Forte Metro K's (1.25" / 85psi / $12)..

I went for the "upgrade" thinking.. more pressure, kevlar belt for puncture resistance, look racy(can an mtb with fenders look racy?)

Long story short, my first impression is that these don't roll as easily or as smoothly as the cheaper 1.5". Only one ride, but we'll see. ...data shows slower too, but maybe I just had a slow evening.

The lesson.. I don't know.. maybe that there is something to wide compliant tires being fast?
