What 180/55-18 means
180 is the section width in millimetres, measured across the tread. 55 is the aspect ratio: the sidewall is 55% of the section width, which works out to roughly 99 mm here. 18 is the rim diameter in inches — the wheel this tire mounts on.
On most motorcycles a 180/55-18 is a rear tire.
The sizes listed for each model are the sizes it is made in. Confirm against the size on your own bike before ordering — wheel swaps change fitment.Every 180/55-18 tire we stock
