Typically that's the result of "tramlining". Cars with wide tires are particularly susceptible to this. Generally caused by slight road irregularities on heavily trafficed roads. Often you cannot see the road level difference. The tire track areas gradually sink a bit especially where there is heavy truck traffic. The tires nibble and fight side to side in this "groove". Some tires make this more noticeable.

The problem becomes exaggerated on Sports (or sporty) cars where the suspension settings are a skewed toward handling response, rather than a hands off boulevard ride. YOu can dumb down the settings (lol...the Corvette guys do this all the time), buy different tires, or just choose to live on the edge...
