Moped Tire Sizes – Dual Meaning of “Size”
A bicycle 16″ tire fits inside a motorcycle 16″ tire.
The “size” of the tire has a different meaning for bicycles, than for motorcycles and cars. For bicycles, the tire size means the outer diameter of the tire. For motorcycles and cars, the tire size means the inner diameter of the tire. So a 20 x 2.125 (OD=20.1 ID=16.0) bicycle tire fits a 16″ moped rim. Conversely, a 16 x 2.25 (OD=20.2 ID=16.0) motorcycle tire fits a 20″ bicycle rim.
You can measure any rim with a tape measure, and determine the tire size. Try to measure the rim diameter at the “porch”, where the tire sits, not the “lip” at the very edge. A 16″ rim will have a total diameter of 16.6″. So don’t count the lip. This method settles the confusion of whether a marking or specification is using the bicycle (tire OD) or motorcycle (tire ID) system. Older mopeds often have 2.25-18 (22 x 2.25) and 2.25-19 (23 x 2.25) tires. They used the bicycle system. Modern moped-size (thin) tires, since the 1970′s, all use the motorcycle system, in the USA.
Some modern electric scooters have an oddball size, 16 x 3.00. It’s a bicycle size, because a 16 x 2.25 bicycle tire fits, but wider. It’s a solid aluminum disk rear wheel, and so the inner tube valve stem must be the 90 degree type. The rim diameter at the “porch” is about 12″. A motorcycle inner tube size 3.00-12 fits perfect, but they are only available with straight valve stems. Tires and tubes for those must be purchased from the dealer or distributor of those electric scooters.
