The first number is the width. The second number is the aspect ratio. It is NOT a size measurement, but a percentage of the width. For example, a 225/50R16 tire has a 112.5mm sidewall.
Your overall tire height is calculated something like this.
Overall height in mm = 2(width x aspect ratio) + wheel diameter in mm
like this-
Height = 2(225x.50)+406.4
Height = 2(112.5)+406.4
Height = 225+406.4
Height = 631.4mm
or in inches it's 24.86
