Nanna, No problem as we freely share our knowledge on this thread and this site. When I'm there, I end to buy 2 - 3 at a time simply because I like to have them on hand for any new to me vintage machines that may need a tire. I do usually change that because I never know what age the tires may be and it's an inexpensive piece to replace.[/QUOTE]
I buy as many as sew-classic needs for the discount - I routinely replace them and belts and felt pads.
