I have a couple of older road bikes. One is an old Japanese bike (1978?) that has 27" wheelsets and gives no trouble in the wheel/tire area. But, the Fuji (1989?) has a real tire problem.
The bike rides fine with 700x23c tires by Michelin that came with the bike. The 700x20c tires by Michelin also work like a champ.
But, when I put on 700x25c (Michelin and Specialized tried) tires on the back --- they rub against the brake housing and it is not usable. Seems I have a "tallness" issue here.
I am new to road bikes, and since these bikes came to me needing a little TLC --- I am not sure what is normal.
Tires ideally will have a round cross section - so a wider tire will also be taller.

Welcome to the 21st century. Many new bikes are designed with very tight clearance between the tires and brake calipers, and also between the tires and frame. It's largely a style thing and has no real advantage (and as you've discovered, limits your tire options). Dual pivot brake calipers tend to make the problem worse. Not much you can do about it unfortunately.
