See at Sheldon's page about centering the brakes: meaning loosening the bolt that attaches the unit to the frame and rotating the calliper until both pads are at equal distance from the rim. Then re-tighten and check once more. You should also check if the wheel is correctly centered in the frame or fork. In case of doubt always refer to your LBS.

As for what wheel to choose, well that's such a complex combination of factors, hard to provide a simple answer. I outlined some of the considerations when weighing up choices in my blog post I linked to in an earlier comment on this thread: They involve a range of factors, including, inter alia (and not in any particular order): strength durability ...

As @Batman says, 2mm is VERY little clearance on a bike. It is more likely to be the frame flexing (more so the chain and seat stays) causing the tyre to move around a bit. I would see if there is a way to mount the stand a little further forward on its bracket. You want to create as much distance as you can between your stand and the tyre as possible. ...

As stated in this answer or this link, the idea was originally that there were 700A,700B,700C tires+wheels which all had an outer diameter of 700 mm with A tires being the thinnest and C tires being the thickest (so A had the largest rim and C had the smallest rim). Eventually, the C variant won out, and people varied the outer diameter by mounting different ...

Pretty much been done to death with evangelistic enthusiasm on many forums. Smaller wheels - more agile and responsive, lighter/stronger, easier to control Larger Wheels - roll better over small obstacles therefore considered faster in straight lines, lower tire pressures (due bigger tire) provide more traction off paved roads. Slower to accelerate ...

The amount a wheel will flex will vary greatly depending on front/rear, spoke count, rim material and rider weight. The pedalling force that drives the bike passes through the rear wheel, so it is not uncommon for carbon rear wheels to flex significantly when a stronger/heavier rider is climbing. For an aluminium rimmed front wheel with spokes that are ...

Might be useful to check if the skewer is tightened properly too. See that a lot in the shop when customers bring their bikes back saying the wheel pulls to one side when they brake. They also have disc brakes, hence why it pulls to one side. :)

Freehubs can be removed from the hub and replaced; it involves removing the axle from the hub and then loosening a fixing bolt with a 12mm allen key. Visit your local bike shop and ask if they have any thrashed rear cassette wheels; if they're cool they'll give it to you free or next to free. Pull the freehubs and hope to find something compatible; there ...

It depends on the type of hub, but most commonly you'll need a 15mm and 17mm cone wrench. A picture of the hub would be helpful.

It's pretty easy if you have a spoke cutter than are willing to run a funny spoke pattern. I suggest buying (ideally second hand) a three speed hub and lacing it into the 16" rim yourself. With a wheel that small with a child on it there's no enough load to make strength an issue, so you can reasonably either lace a 20 spoke rim to a 36 spoke hub using ...

You could try adding sealant to your tubular tire. Tufo Tire Sealant, Stans's No-tubes (and other tubeless sealants) can be used to deal with small punctures. Most recommend not using the sealant as a preventative measure, but more so as an after the fact solution to quickly fix punctures on the road. However, Tufo Standard tire sealant says that it can ...

Use puncture resistant tire liner like that one: http://www.flowbikestore.com/band-zefal-puncture-zliner-blue-26

I don't think that its a good idea given that in a few months, you're going to want a 20 inch bicycle for the child. IGH's wouldn't work since the hub width is likely smaller than standard, and mounting a derailleur would be a problem as well. Also, if you were to find a compatible hub or whatever (given the 20 spoke constraint that andy256 mentioned in the ...
