I like the idea of low rolling resistance designs, at least for the non-driven tires.
While I understand low resistance tires *tend* to grip less well, there should be an ability to have the tire behave differently under torsion (braking) compared to the normal operation where the tire wants to provide the least resistance for best mileage.
Would low resistance tired provide problems handling in rain? Or would the need for improved rain performance only be during braking?
Deformable tires? Perhaps in our future.
