This tire has a camber correction of 2,3, or 4 degrees built into it's cone shape giving more rubber contact with the road. Obvious issues of a conical shape have theoretically been corrected with spiral tread groove. For this to work right, one would still have to correct for toe, but you'd do the same with any tire. This looks like a promising solution for those running huge camber due to lowering.
