I've used 25mm Power Endurance(and PRO4 Endurance) tires on many different bikes, and always been happy with their performance. On 17mm internal width rims, they measure 27.8mm [MENTION=117766]100psi[/MENTION] after stretching.

Power Endurance tires feel a little more supple than PRO4 E or Krylion2 E tires, but mileage is about the same.
