small front tire; large back tire

[kap]

Testing a 700C-25 front tire on my commuter (low end road model) bike while still using the 700C-28 rear tire. On this morning ride to work, I could feel the jarring from the front tire. Is it worthy to upgrade the tires?

....doesn't JLo have this exact same problem....??

did you check pressure on both tires? pressure could also make the difference

Man, I just realized how the post's title came out so wrong. Ugh!
I meant "thin" tire versus "thinner" one.

I won't pretend to know much about this, but wondering why you want a smaller tire on the front? It won't impact wind resistance or speed or rolling resistance much at all, while reducing comfort. I remember an article by sheldon brown analyzing tire width and pressure (this was focused on touring, not racing) and basically there were was all sorts of complicated physics involved, but a larger, wider tire can be lighter and faster than a more narrow one, depending the sidewall.

seacrest stole my thunder.

that is one dope Schwinn.

I used to polish the fender on my bike weekly. not to mention I had a bad-ass slick on that bike, too. whitewall.

I figured a thinner tire with no treads would produce little to no rolling resistance hence faster and smoother ride. Of course, correctly inflated tire would only improve that. Ahem, I have never said I made it though my college physics class.

I try to run 32C when I can -- worth the extra comfort.
