If you've been calling it tire height then yes you have lol. This isn't a contest, you asked me to clarify and I did, so don't get all butt-hurt. Buying wheels and tires has nothing to do with the terminology being used so you could have bought a million wheels and tires and that doesn't change the meaning of those numbers.
Straight from http://www.tirerack.com/tires/tirete....jsp?techid=46
"Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.
The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall."
