Air pressure in the tires should be equal on each side - also, tire tread wear differences would have a small effect. If there are no descrepancies here, then you must have a suspension issue (slightly weak spring, control arm resistance difference, etc).

I would think this is more of an esthetics problem, rather than something serious.
