I used to watch a lot of airplane landings and take-off. My favourite moment is when airplane tyres touch the ground. Friction produces a lot of heat and hence, smoke.
But i wonder, why not pilot start rotating wheels before landing and match the speed of wheels such that it doesn’t cause any friction.

The wheels have to stop eventually…. and there’s going to be a crapload of friction regardless of if they’re already spinning or not.
Here’s a video of airplane brakes being tested:
There’s a loooooooooot of engineering that goes into airplane landing gear….. like there are people that wrote entire PhD dissertations on the subject…..
