The bearing is worn by the very act of holding the clutch. The rear tire - hm, it would be nice to do some math about it. Until someone competent does it, please don't take it as a fact, it's more like a theory of mine. But applying force to the road (accelerating or braking) wears the tire more than just rolling, and I suspect that wear is not linearly proportional with the applied force (like aero drag is calculated from the square of speed and road damage is proportional with the 4th power of weight per axle). So acceleration/glide cycles probably won't give the same average as the less force needed for keeping the same unchanged speed. Sorry, I don't know the necessary background
