I got some 19.5" tires lst year for another forum member. I remember they were Goodyear G series radials, I think the model was 142, or 147, I will verify this. They were about half the price of the Michelins, with similar coverage for replacement to the Michelins Dennis is talking about. Sooo, if you are planning on driving your MoHo a lot, go with the Michelins, but if it is going to sit most of the time, and the tires will dry rot before wearing out, you should take a look at the Goodyears.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
