Save your tyres as you never know when they might let you down
looks like a forthright opinion to me right there.
Once again, the logic leaves a bit to be desired.
Firstly, to taxi at such speeds would require multiple brake applications or you to ride the brakes to limit the speed to 15kts. Now we ALL know that brake wear in modern jets is based on number of applications and not whether the application is heavy or light braking. All of which would cause a large increase in brake temperature, more of an issue on a short turn around, and have little effect on tyre wear.
Do you realise that even at Max LDG Weight, and A320 will accelerate from 0-30kts without the application of any power above idle?
Secondly and probably more important and techincally correct is the Manufacturer's recommendation to allow the aircraft to accelerate to 30kts in a straight line..... as already stated above.
That being said, you are perfectly correct if your aim during taxi is to milk loggable flight hour, piss off any other operator taxiing behind you being forced to ride his brakes.
