Thought about going with a set of their tires this coming season, but my 'rents bought me some overpriced, over-hyped, long lasting tires for Christmas. Maybe next year Chris.
One problem I can see is now: Shinko may feel like they can "up" their prices like the big boys with the exposure and flock of customers that didn't know they existed. Shinko has to recoup the money they spent on advertising, which will probably be tacked on to the sale of each tire they manufacture.
