3 You did not mention anything about the fork so i will assume the fork works fine.

Between the 3 my fav is number 1.

Sure a 700x23 will fit. The rims are 700C or you would not have been able to put the tires on the rim.

My theory, you have a 650 frame in there, the fork might not be the original either.
Did trek make the 5000 back in 1989?

I have a Nishiki Olympic 12 with 700c 23's with plenty of clearance it would seem you have frame that uses a 650c wheel.

kevink81, Looks to me that it's a case of manufacturing tolerances and the brake bridge was installed slightly low. That combined with a "true to size", or slightly "large" 25 mm tire and tolerance stack up occurs. It's quite possible that another 25 mm model or brand of tire would fit. As that could be a PIA to determine I suggest using 23 mm tires.

Did you read any of the above postings? It is nearly a certainty the frame was NOT made for 650c wheels.

I think you grabbed the wrong quote, but yes they did. Check out the catalog: https://vintage-trek.com/TrekBrochure1989.htm

If the bike originally came with MTB (ISO 559) rims the radial difference between then and 700c would be even more pronounced at 31.5 mm and the brake reach would have to be in the BMX range. Even more unlikely.
