Hello, I recently replaced the Cush drive rubbers with ones I had sourced online from wemoto. I used bits of inner tube to fill the gaps but still had a lot of play on the wheel. So i took it to my local yammy dealer and they said that the ones I had fitted were too small and that I would be better off using the ones they could supply. Would I be better off putting more inner tube in with the rubbers or change the rubbers completely for the 'better' ones? The new ones are less than a week old.
