Front scooter tire Hoop B03 by Bridgestone. Its dimensions are 110/70-16, meaning it has a width of 110mm, a profile of 70, and can be mounted on a 16" diameter rim. The profile of the tires, which is the height of the tire's sidewall, is always referred to as a pure number without a unit of measurement as it is a percentage of the width. For example, a 100/90 tire has a width of 100mm and a profile of 90, meaning it has a profile of 100 x 0.90 = 90mm.
