How to save up to 74 watts on tire tech

Wheels and tires make a lot of difference in biking (as in Formula car racing)  Here are some tips from a video and may be if we want to ride faster, we can implement some of the tips and suggestions

There is not much advantage/loss/gain on the following:

      1.  Tire weight
      2.  Tire width (which is better 23 mm or 25 mm?)   From competitive cyclist
      3.  Clincher vs tubular?

But much can be gained from:

     1.  Tire pressure  (if you are riding on rough roads inflate your tire to only 60 psi, on smooth concrete or asphalt only 100 to 120 psi.  Wrong tire pressure can make you lose power.  This was aptly demonstrated by a rider in Paris Roubaix race who just inflated his tire to 60 psi on cobble stones and was way way ahead of his competitor

     2.  Tire compounds  you can save as much as 27 watts on modern tires with graphene compounds or cotton  inside.  (the graphs show even more)

     3.  Tire rim combination  (it is better to have wider tires and narrow rims)  They are more aerodynamic

     Observance of science and physics can make you go faster.
