In order to avoid a tire thread from going off-topic I have started this new topic.
Tramlining the definition (thank you Tire Rack)
All the options available to reduce tramlining affect mileage except for maybe the last one on this list
* Using lower tire pressures reduces tramlining (increase fuel consumption)
* Wider tires can reduce tramlining with the Insight (increases fuel consumtion)
* Adding spacers to the rear rims to bring them out further should help (but it brings more of the rear tires into high speed airflow therefore fuel consumption will probably increase slightly)
* Changing the front wheel alignment so it has "Toe in" like most cars do, will reduce tramlining (but increase tire wear and fuel consumption slightly)
* Adding vortex generators at the leading edge of the front undertray.

Tramlining the definition (thank you Tire Rack)
http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=47¤tpage=47The term "tramlining" is being used to describe when directional control is disrupted by the vehicle's tendency to follow the longitudinal ruts and/or grooves in the road. It's name could be compared to the tram or trolley driver who does not steer because his vehicle follows the path established by the tracks.
