Seems like one could design the tread (or an extra rubber tab) to catch the wind and self spin.

- ncmncm 5y agoAnd, as I said, these ideas have been explored in depth, and abandoned. Nothing has changed in tires or landing gear, since, to merit going back over everything that was tried. Suppose your stuff got the tire spinning at the circumferential rate of 20 knots. The plane touches down at 130+ knots. Is the decrease in rubber deposited noticeable? How fast would you need the tire to be spinning to make a noticeable difference? How much does your extra apparatus weigh? How much extra space does it take in the wheel well? The extra weight has to be carried throughout the flight. Space in the wheel well is tightly constrained, because it is near the center of gravity of the aircraft, where cargo space is most valuable, and where the wing spar crosses through the fuselage. Everybody thinks of spinning up wheels. Thus far nobody has had answers to the questions that led to acting on the idea.
