What If Car Tires Could Be Like Bicycle Tires?
This may take some explaining....
If you look at the raciing bycycles, you will notice one groove in the middle. It is the only contact with the road when inflated to about 90 psi. Not a comfortable ride, but the rolling resistance is very minimal.
This leads to the question of how to practically adapting this to cars. If someone could devise a safe way to get a car tire to go from nine inches of thread on the pavement to one inch, the rolling resistance would be greatly reduced. Of course, the only place to do this would be open roads.
Wear considerations would be the greatest concern after safety....
