I currently have 700 x 40 tyres fitted. I don't know what size the
rims are as they are not marked. The tyres are the original ones fitted
when I bought the bike. How can I tell what size the rims are? What's
the narrowest tyre I can fit?
Pretty much any 622 mm ("700c"😉 tire will fit, but generally the tire
should not be narrower than the rim, and preferably at least a little
bit wider.
Hold a ruler up against the rim to see how wide it is.
I have never seen a 622 rim so wide that would not work happily with a
32 mm tire. There's not much point in going narrower than that unless
you're riding competitively.
