first question, will they work together. I know the pulley moves the tire forward a little bit. So when my stock tire wears out will the commander II work? And does the pulley fix the speedo issue? If you have both of them installed will that have a negative effect on the gearing and the speedo? I think the barons and larger tire alone make the gears a little taller and fix the speedo. But using both, will the speedo now be slow and the gears too tall? thanks so much.
