Replacing 14" x 1.95" With 14" x 2.125"? I have a super quick question here, my daughter (she's 5 years old) rides her bicycle extensively, to the point of the actual tire has worn clear through.

I didn't think it would be this difficult, but I can't seem to find a direct replacement for her tires anywhere (her tires are 14 x 1.95).  I see plenty of 14 x 2.125 tires, would that work and be a direct replacement that'll fit?

I'm not sure what else to do at this point, but if we can't find new tires then we'd be forced to unnecessarily buy a whole new bicycle for her.

Any thoughts or ideas?  I have searched common stores, as well as checked online and there just seems to be no 14 x 1.95 tires available.

Thank you in advance!
14" tires are actually quite common on department store bikes (Wal Mart, etc), but they are not found on "bike shop" brands. I think this is where some of the confusion on this issue has come in.

You will almost certainly be fine with the slightly wider tire. For one thing, there is no true standardization on tire widths. I.e., every company uses its own gauge for what it means to be 1.95", etc (I once had a 2.55" tire from brand X that was narrower than a 2.2" tire from brand Y).

To be on the safe side, make sure you have a little clearance wherever the tires pass the frame or fork; but I would bet money that the 2.125" tires will fit, and on top of that you probably won't be able to tell any difference between the old and new tires.

EDIT:
Apparently I don't have enough points or something to comment on the answer that links to the Schwalbe website. I was going to say, "Those tires with fractional widths on the Schwalbe website will be entirely different from the tire with a decimal width mentioned by the O.P. If the O.P. gets a 14" tire with a decimal width he will be fine. In the USA I doubt there is anything else to be had."

Finally, if Wal Mart does not sell replacement tires for its own bikes (regardless of the marked width), any bike shop can order the correct tires for you and offer you a guarantee that they will fit.
