      The first number is the width the second the Aspect ratio in %.

      So a 245/40 would have a sidewall that is approx. 98mm tall. The 275/40 would have a 110mm sidewall. Taking a Yokohama AVS sport for width example the 245/40/17 is 9.8" wide and the 275/40/17 is 11".

      In short the 245 is narrower and has a shorter sidewall than the 275.
