no. you're wrong. read the FAQ article again. those numbers(50, 45, etc) are called an 'aspect ratio'. it means that the sidewall height is X percent of the tire width( the 205) from the widest points.
example:225-45-17
is 225mm from sidewall to sidewall(across the tire)is (225mm*.45=) 101mm high sidewallon a 17 inch diameter wheel.
