The ETRTO size is the best size to check if the inner tube you're buying is the same size as the one you currently have on your bike. These are numbers written on the tire in the same format as your postal code, for example, 32-622. This means the tire is 32mm wide and fits a 622mm rim. Therefore, the inner tube we're looking for must have a diameter of 622mm and a width appropriate for our tire.
