I agreed, and if you want to know the tire's sidewall height (from rim to tread) simply do this formula...
/R16 50 indicates the sidewall height.
225/24.5=8.86" (wide of the tire) now multiply it by 50%. (.50) = 4.43" from rim to tread.
if the tires was 225/70
/r16 225/24.5=8.86 x .70 = 6.20"
why 24.5 ? cuz is the number of milimeters per inch.
