Univega tire OD problem
I have a Univega Super Strada frame (unclear what year) which has non-original 700c wheels. I have 700x25c tires on the bike, and there is only a hair of clearance between the front tire and the brake caliper. I just replaced the rear wheel, and the rear tire is rubbing on the brake caliper. I don't know what wheels/tires this bike originally had, but my understanding is that 27" wheels have greater tire OD than 700s do. A lot of the components came over from another old 80's univega, which had 27" wheels but I couldn't get the 27s onto this frame at all - thus the 700c wheels.
Is it worth trying 23 wide tires vs the 25s that are on there now? The current tires are also 'flat resistant", could that be part of the problem? I use this bike as a commuter, and am not crazy about the idea of a smaller tire than 25.
Any ideas would be appreciated.

I'd get a different bike for commuting that could at least take a 28c tire and fenders. I know that doesn't solve your immediate problem but I think it is the best long term solution.

I did a quick google search and all the Super Stradas I see appear to have come with 700c wheels to begin with, and yes, they have fairly tight clearances. In your case, the first thing I would do is measure your tires and verify how wide they really are before making any decisions (tire width can vary depending on the rims they're installed on, and it's not all especially unusual for tire makers, even highly respected companies like Continental, to mark tire sizes that differ somewhat from real world observed values.)
If you give us more details about your tire/wheel combo (pictures may help) you'll get more specific answers.

Some tires, like the Michelin Pro Service Course are greatly oversized in the 700x25 size and measure close to 28mm wide, depend on rim width. What tire do you have?

Yup - and some others run undersize. For example, I can put 700Cx28 Contis, but not 700Cx28 Specializeds, on my Bianchi.

This is one reason race bikes can sometimes make mediocre commuters.
