Weight has a big influence on wear caused by braking. And when I compare the wear of similar tyres on our tandem and my MTB there's definitely an influnce of weight.
Rolling resistance also increases linear with weight.
Steering power and rough road surface also inluences wear.
But driving power also plays a role naturally.
