    Widest tire for a Alex DA22 Rim

    I am thinking of configuring an entry level GIANT OCR3 road bike I have into more of a winter/commuter bike. I almost never use it as a road bike so I was thinking of putting 28 or 32C Cyclocross tires on the bike. A few issues that may not be resolvable....

    1: Can I fit a 28 or 32 C tire on my cheap Alex DA22 road rims? The rim width is 13.9mm (see photo)
    2: It is a road bike with Caliper brakes, can I inflate the tire after I've squeezed it past the brake pads? Or is this just something you don't do without Cantilever brakes and the right frame/fork?
    3: Any ideas on how to guess if I will have enough frame and fork clearance for the wider tire?

    I attached a photo of the basic type of tire I was thinking in a 28C, most of the 32's look too large and knobby, I think.....

    If you just aren't supposed to convert a road bike into a Cyclocross-ish bike, someone should be frank and tell me it's a bad idea!

    Thanks!

    1: As long as the bead diameter is the same, sure you can.

    2: You sure can.

    3: Try borrowing a wheel from a friend with the size tire you're considering and pop it in your frame.

    4: It's your bike, make it fit your needs. If it'd take too much modification/kludging to get it to work, that's when you consider buying a bike built for the purpose intended.

    I probably would not go beyond a 28 on a 14mm rim.

    I've done 32s on a cross bike, should be OK.
