What 140/70-17 means
140 is the section width in millimetres, measured across the tread. 70 is the aspect ratio: the sidewall is 70% of the section width, which works out to roughly 98 mm here. 17 is the rim diameter in inches — the wheel this tire mounts on.
Depending on the bike, a 140/70-17 can run at the front or the rear.
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 140/70-17 tire we stock
