O.K....so I ordered these new tires for the trike. They are SweetSkinz http://www.sweetskinztires.com/sweetskinztires/

The order was received but one of the tires did not have the reflective capabilities it should have. In any case I am awaiting the replacement for that one. I mounted the rear tire and rode it tonight. Seems to handle quite well. Has anyone else tried these???? They aren't any more expensive than any other tire on the market so I thought I would give them a try. I'll post photos as soon as I have all three mounted.
