I know decades ago they experimented with spinning up a planes wheels before landing with electric motors to cut down on tire wear, but it eventually was scrapped. Maybe that’s ready for another look see as well...

If it worked.. then a ram air turbine would be easier than Electric maybe ?

Yes, and I remember free wheeling wind turbines as well. Apparently the weight and complexity of those systems didn't 'pencil'.

This might, since that ability is in addition to the primary fuel savings goal and is therefore essentially free, at least for the front wheel.

I like Gaffer's idea. Perhaps the tire replacement savings on the front wheel will drive revisiting doing the same for all wheels?

Before adding anything onto a plane they need to figure out the weight to benefit ratio.
Adding anything to a plane adds more weight therefore uses more fuel.
