There is a technology triangle in tires involving treadwear, traction and rolling resistance. In order to get good values in one area, one or more of the other areas has to be sacrificed.
So carefull selection of tires with the right compromise will pay dividends.

True to a degree. However by first wanting to improve rolling resistance and then by applying new approaches and technologies the triangle restrictions can be exceeded. I'm sure few would argue that overall tire performance of a 1960's tire would be the same as a modern one due to the triangle.
Case in point - my Michelin X-ice II's. They have the best ice traction I've ever had without studs, and rolling resistance roughly equal to my Kumho LRR summer tires. True deep snow traction not yet tested but I expect they will be very good because the tires earned the mountain/snowflake logo. I used them at Watkins Glen for the 2012 Green Grand Prix, experienced excellent dry and wet traction.
