Yup, its not a measurement of mm. Its a ratio between the section height and width expressed as a %
eg. a 40 profile tire with 205mm width will have a section height of 82mm
just proved that theroy wrong my lancer as 205/45 with a wall height of 48mm

All well and good but you try and tell me that if my tire is 205 then 45% of that would be around 90 mm I don't have 90 mm walls. What am I missing
