The bike will ride like a rock with that sort of pressure, and you may or may not actually be faster. There is a point of diminishing returns regarding tire with and inflation pressure, beyond which you're just making the bike less comfortable. In general, a quality 35mm tire inflated to reasonable levels isn't going to be slowing many non-professional riders down. Narrower tires feel faster (and may even be faster in some settings), but data shows that there just isn't a significant difference. Professional riders have been increasing tire width for a number of years now, even riding 30-32mm tires lately. It's mostly just personal preference.
I agree with
xroadcharlie that
different tires in the same size will be as transformative as
narrower tires.
Yeah I went to a bike shop and talked to the guy there, he really discouraged me from going down from 35 mm. He mentioned you got worry if you shave too many mm's off in tire width that you also need to worry about the rims too. Then he mentioned you got make sure its going to fit in your Fork right. He basically shot off a whole lot of reasons why he thought going down to a 28 mm tire or even lower 25 mm on a hybrid he thought was a very bad idea.
He thought I should just stick with the 35mm tire and choose a different kind of tire.
I also talked to a Trek representative and he said I could get down to a 32 mm tire with my rims, but I shouldn't try to go any lower than that.
so the question is what is faster lower rolling resistance... getting my same tire that I have now on the fx2, but in a narrow size 32 mm or getting a different 35 mm tire that is suppose to have less rolling resistance... like the 35 mm hybrid tire that was mentioned in a previous post...
