The alphanumeric hieroglyphics on a tire's sidewall offer a variety of info. Size can appear in inch, metric and/or alphanumeric denominations. All three interpret the size in terms of its width, aspect ratio and diameter of the intended rim. Here 160 is the cross-section width in mm; 90 is the aspect ratio (the relationship of the tire's height from the rim to the road to its width, expressed as a percentage of section width); H is the speed rating.
