Tyres - how to work out which size I can put on

[SquareDaff]

I have a hybrid bike with 700x35 tyres on. They came with the bike and now have a couple of thousand miles on them - so will probably need replacing soon. As my ride is mainly roads I'd like to replace them with narrower/slicker tyres. Is there some science to working out the minimum width of tyre I could get away with?

If you know the rim width, Sheldon has a chart http://www.sheldonbrown.com/tire-sizing.html at the bottom of the page.

how do you find out the rim width?

You should be able to find it out if you know what rims are on the bike e.g. http://www.mavic.com...lon/rims/CXP-33 take 19-28mm tyres

Using the table on Sheldon's site, this rim would take something like 20-35
