most of us notice that roads are rarely level, left-to-right, and this is done for proper water drainage. On a divided highway for example, the leftmost lane will be sloping down towards the median (at least on the roads i drive on)

if you drive on the left lane, your car will tend to steer towards the left, which is lower (and this is probably helped by the pronounced caster of the benz's front wheels).

question is: what kind of tire wear can i expect from prolonged driving on this type of surface? (there must be some tire wear, since there is a force acting on the steering). Will this be taken care of by proper and regular tire rotation?
