They are the same width but the sidewall is shorter on the 40. the numbers 50 and 40 in the tires you mentioned is the sidewall size as a percentage of the width of the tire 240/55 has a 133mm sidewall and a 240/40 has a 98mm sidewall as a example. they are both the same width tire.

240/55..... 240 is the mm width of the tire.

55 is the percentage of the sidewall width.

240mm wide, by 55% of the sidewall width = 132mm tall from the ground to the rim.

240/40.....240 is the mm width of the tire.

40 is the percentage of the sidewall width.

240mm wide, by 40% of the sidewall width = 98mm tall from the tire to the ground.

Basically..... the 240/40 tire is 68mm shorter over all, and 32mm shorter, for ride height in the rear, VS the other tire.
