700x28c tire question
i just aquired an old Ross Signature with 700x28c tires (also listed as 28 x 1 5/8 x 1 1/8 on the tires).
the bike is in seriously amazing condition, except the tires have a ton of wear and are beginning to split.
i've been reading and rereading Sheldon Brown's articles on tire sizing, and my question is, what widths of tires can i put on my bike?
i don't know the size of the rim, and i don't have any way to measure it, unfortunately.
if i put a 700x23c tire on, would it just come loose?
