It would be nice to see some data, article just said there is an improvement. How much? Compare to what? Obviously there is parasite friction and heat dissipation issues that still can be addressed.
Traction and rolling resistance are explaining the same thing, just one is negitive and the other positive. Theoretically, in a perfect model these two elements, grip and roll resistance, are directly related.
