No, a 225 tire is not necessarily taller than a 205 tire. The first number in tire size (225 or 205) refers to the tire's width in millimeters. The height (tire's aspect ratio) is the second number, represented as a percentage of the tire's width. Therefore, the overall height depends on this aspect ratio and the diameter of the wheel the tire is mounted on.
