    29 x 2.25 tire on 700c rim
    Hi, would i be able to fit a 29 x 2.25 tire on a 700c (622x14mm) rim? Thanks for your help. Specs of wheel: Alex AKX - R1.0 Double Wall Aluminum, 700c. http://img.tapatalk.com/d/13/07/14/8y3edeja.jpg

    It would probably mount up okay, but the ride would be terrible. with such a narrow rim, the tire would try to roll over on its side wall. it might actually fold over, right off the rim.

    Thanks for the input! Would you say the same goes for a 622 x 19mm rim? Sorry for being a pain in the arse. My budget is very limited for purchasing actual 29er rims :(

    19 millimeters would certainly work better. What kind of riding are you planning on doing on these wheels?

    ^What they said^. Running a 29 x 2.25 tire works best on a rim wider than 23mm ID. Otherwise, you'll get squirrely, unstable handling; you'll point the wheels, but the tire will go where it wants to go....scary and frustrating.

    OP, No need to apologize, as the term 29-er is pure mktg hype (overall height).

    All 700 c rims are spec'd @ 622, and not too long ago were all based on narrow(er) road touring rims.

    Could you mount fat rubber on a 14mm internal / 19 mm external rim? Yes, with a tube and at 35-45 psi it will work. (I did for years on an early set of stock Bonty Race Discs.)

    Yet, like the earlier post implied it would not be ideal - fat tires really like and perform better on wider rims. YVMV.

    So is there such a thing as a "fat tire" for that size rim -622x14mm?

    I do it often. Fits fine. I have a wheelset with 19mm (13 inside) rims. Use tires from 23mm to 2.4". Mostly 35-42mm roadish or 1.75 (45mm) to 2.1" knobbies.

    The wider tires can get squirmy unless you run the pressure higher. Some treads may not handle well (but the same can be true for narrow tires on wide rims).

    Note that a 23mm rim has an internal width ~17mm. Your rims are ~20mm external.

    oof, 2.25" tire on a 14mm ID rim? be careful, it might fit but you're at risk for pinch flats

    see also Tire Sizing Systems

    I run Michelin Mud 2 30C cyclocross tires on my old 622x15C factory rims & they work great.

    For a 2.25" tire you should be using at least a 19mm ID rim and really a 23mm or wider would be a better idea.

    IME too narrow a tire on too wide a rim increases the chance of pinch flats.
    A wide tire on a narrow rim does not.

    Wider rims are good for 2.25 tires, but the OP wanted to use his existing wheels.
