Spinning wheels before landing adds to the energy of the aircraft at the threshold, energy that has to be disposed of via the brakes before you come to a stop. Tyres are cheaper than brake packs, so pre-spinning is 'out' - QED.
I recall a similar conversation with a car fleet engineer who hated to see vehicles being braked by engaging a lower gear, putting reverse strain on his beloved gearboxes. "Brake pads are cheaper than gearboxes" he said.
