Tire size?

I have a 85 trek 620 that is running 700 wheels and canti brakes.

I have 28's on it now, any idea how big of tire I can fit?

Dyad rims.

Measure the distances between the fork blades and the seat and and chain stays at the point where the tires are widest. You'll need some room on either side of the tire, probably 8mm. Remember that the width of the tire stamped on the tire and the actual width might vary.
