Welcome to the world of bicycle tires. Here's what the late and great
Sheldon Brown said about it:
Dishonesty in Sizing
Competitive pressures have often led to inaccuracy in width
measurement. Here's how it works: Suppose you are in the market for a
high performance 700 x 25 tire; you might reasonably investigate
catalogues and advertisements to try to find the lightest 700-25
available. If the Pepsi Tire Company and the Coke Tire Company had
tires of equal quality and technology, but the Pepsi 700-25 was
actually a 700-24 marked as a 25, the Pepsi tire would be lighter than
the accurately-marked Coke 700-25. This would put them at a
competitive advantage. In self defense, Coke would retaliate by
marketing an even lighter 700-23 labeled as a 700-25.
This scenario prevailed throughout the '70's and '80's. The situation
got so out-of-hand that cooler heads have prevailed, and there is a
strong (but not universal) trend toward accurate width measurements.
