Don't know about how old yours are, I ride a pre FC from 2009 with 22 front and 25 rear. Works great.

22 will be fine. There's absolutely no need to match the tub width to the rim width. You could probably run wider than 22mm also, but 22 should be good for aero on that wheel and better for rolling resistance.

It's worth running sealant in tubulars too, since they get kind of expensive to replace. I use flat attack so that it doesn't dry out and ball up inside the tyre. Check out the sealant article on ST (http://www.slowtwitch.com/...t_-_Part_2_4155.html) and make sure your tubs have latex tubes...

Thank you both, that is very helpful

I use a 23 on a 19mm rim, works gr eat, yours will also work.

res, non verba

Heck! I run my CX tubulars (34c) on 19mm rims. Run what makes you happy.

I'd recommend 23c or 24c tires for comfort and speed

there are some nice comfy 23 and 25 size tires out there, no sense using something skinny

compatability wise, your wheels will be fine with most road tire sizes.

Aerodynamics wise, sticking with something under 23mm is probably advisable but there aren't really any decent 19mm tubular tires out there.
