Dreamt I was riding my first road bike down gravel roads last night and it worked better than expected. Bought in the early 80's when I was in the Air Force, this was my first real bike not from a hardware store. Dug it out of the garage this morning to check everything, maybe an easy ride if it warms up. Front tire inflated easily (Presta), but had to reconfigure pump for back valve, which inflated and immediately emptied. Not only is it a Schrader but it doesn't have an inner core. Yeah, it's been a while.

If someone wanted to get new wheels and tires for this what size would they shoot for? That is, is there a common, easily obtainable size that would fit?
Update: I should have said "rims" and tires.

28x630 is the ETRO size you need to match that tyre.

Pay no attention to 27" as that relates to the outer diameter, so you get a different size internal (rim) dimension for different width of tyre so there's always a chance a 27" tyre doesn't fit a 27" rim.

Tire Sizing Systems

Several different systems of size markings for bicycle tires are in existence. The modern ISO system is not as familiar as it should be, this article explains it.
