It is true that turning makes front tyres wear, even at parking lot speeds (turning with power steering when the car is stationary introduces significant wear, relative to the distance driven, if that can be measured for a stationary car). At higher speeds it depends a bit if the car has under steer or over steer but in any case fronts would be more affected. In any case, also rear wheels are needed to make the car turn! At a constant turning radius, the rear wheels actually "bend" more. But normal driving at turns usually makes fronts wear more.
Fronts wear more at braking too because most of the brake force is applied to the fronts (modern MBs can increase the rear brake force when stability allows).
Rear tyres wear from engine braking but the real thing is to make the car move. As long as we talk about RWD cars, this makes the rear tyres wear.
At straight roads and constant speed the wear would be on the rears but here the main factor is actually wheel alignment. Toe-in makes tyres wear but MB has quite strong toe-in at the rear too, unless changed by re-alignment. This is to make the car as stable as possible at full deceleration from 250 km/h to which the car is built (I'm only talking about diesels, AMG models may have been built for higher speeds).
Clearly from the drivers comments already one can see that both are possible, rear or front wear mostly, and even wear in-between. It still is a surprise to me to see this many cases of more front wear. Most of my cars have been RWD and I've never seen a RWD car wear more fronts. My assumption would be that this would come from a lot of city driving. I'd be interested on comments from those who have strong front wear. Do you have the wheel alignment at factory figures? Myself I'm doing both, most kilometres from outside cities, don't know time wise. I'm not burning tires more than occasionally leaving traffic lights "rapidly".
