    fitting smaller tires on 29er rim

    wondering what size tires I could put on my 29 rim. For instance can I put 700 tires on that rim and if so how wide do they need to be? 700 X 35? I need to get a tire for a trip that is lower profile as to fit a trailer behind.
    Thanks

    Depends on how wide your rim is. I had asked the folks at NoTubes just how narrow a tire I could safely fit on a 355 rim, and was told 25mm maybe, 28mm certainly. A 35mm tire shouldn't be any problem, I'd guess, for most rims under 30mm in width.

    700C = 29"

    Same bead seat diameter.

    As with any wheel diameter, any tire wider than the outside of the rim will work.

    The trouble with common sense is it is no longer common

    Depends on what kind of tread it has. If it's a slick you should try to get a couple mm's wider than the rim width. I'm running a 32mm slick on a Salsa Semi and that works well. The 34mm Mezcal on the front will squirm on the side knobs if I lean it too much. Those knobs are higher up since the center tread is lower.

    What Shiggy said. Go at least as wide as your rim and you should be fine. I've run 700x23s on 23mm Salsa Delgados with no problemos.

    I've used 700x28 on 26mm WTB Speed Discs with no issues. The rim is more vulnerable to smacking on a rock or something (my commute is partly on dirt), but I never had it happen. Sounds like you're talking mostly road use... you can go very narrow with no issues.

    (unless you don't have studded tires)
    (no excuse for that either)

    I have run 28mm tires on Blunts, Edge XCs and Edge AMs without issue. Road riding has a history of using rims as wide as the tires.

    I have 25mm Rubino Pro tires on Salsa Delgado Cross rims. They work great:
