I ride a 2006 Vulcan 900 classic. The Dunlops are bald so I purchased Shinko 230 Tour Masters for the front and rear. The Dunlops say Tube Tire and I purchased tubeless tires. A friend said to throw the tubes in the new tires and a shop also told me that you need to use a tube always on a spoked wheel. Is this true? Do I need to use the tubes? Also if so should I re-use my current tubes if they look ok or just buy new ones? And suggestions or feedback on Shinko tires on your Vulcan Classics would be appreciated.
