Real world flying, tires have speed limits, extra speed
burns the tires up and the stop gets very expensive.

You can say THAT again! Not in the GA venue of course, but the tire pressure
on a T38's mains is 250psi. When you blow these suckers, you'll think you've
been shot!
The T38 rotates at 160, max tire speed is 220, and gear speed is 240kts. In
this airplane, you are accelerating so fast on takeoff that rotation, and
gear retraction are practically one fluid motion....and indeed they HAVE to
be, to meet the Vle parameters.
Of course, GA airplanes are a bit tamer!! :-)
