    Will they fit?

    Hey all,

    I have a pair of brand new Performance GT2/k 700x25c tires that were recently given to me and I was wondering if these tires would fit the existing wheels on my Giant Cypress DX? The current tires are Kenda 700x40C. I was planning on switching to a narrower tire at some point and these just happened to fall into my lap. Just not sure about the fit?

    700X25 are awfully narrow for the rim that will mount a 700X40!

    I really don't recommend that idea.

    Thanks Tom. I thought they might be too narrow, but grabbed them anyway since they were free. Might make good trading material later on.

    Socalrider, The rims are the the ones that came on the bike from Giant, not sure what size they are.

    Try calling your dealer or Giant? I know in the rear of my Trek I'm running a sun RhynoLite rim, and I *can't* go below 700x32. Which is fine, they roll fast enough for my tastes!

    Specs state that the rims are "Alloy 32H" and the tires are "Cross Comfort Anti-Puncture 700x40C, Slime Sealant-Filled Tubes".

    Anybody have any idea what the width of an Alloy 32H rim is?

    Alloy 32H are your hubs -- 32 hole -- I do believe.

    The Cypress is a comfort bike, so runs 38-40mm tires with wider rims to match. Your 700x25 tires are intended for a road bike with much thinner rims. 'Twouldn't fit. performancebikes.com has a nice image illustrating this fact if you take a look at any of their tires and then click 'Sizing Chart'.

    I see what your saying mongo. Just noticed that they list Alloy 32H for the rims and Alloy 32H QR for the hubs on the full spec tab of their web site
