Here's a question.
Every time an aircraft lands, the tyres hit the runway at over 100 mph, which obviously takes a large amount of the tyre was, as evidenced by the tyre smoke.
Would it not be possible (and presumably not too expensive) to have the tyres "pre-rotating" at the ground speed of landing?
You would obviously lose a very small amount of retardation that you get currently, and there is a cost involved, but presumably there would be a net gain over the life time of the aircraft in terms of tyre costs?

If I was a tyre maker for aircraft, I think I would be happy not to do something that would reduce the wear rate.......
I can see why there would be no benefit for the tyre manufacturer, but not so with the aircraft manufacturer / airline.

Surely its a free part of the braking process?
Free, but negligible, surely?

or we could dispense with the undercarriage all together?
