I get my car aligned usually once a year at the Subaru dealership. Can anyone shed some light on why the treadwear would be so uneven on only the passenger side of the car (front and rear tires look almost the same). The tires wear much more evenly on the drivers side. My summer tires showed the same strange treadwear pattern too.
Passenger side front tire:
Close up of the outside of the front passenger tire:
Close up of the inside of the front passenger tire:
Driver side front tire:
I'd like to get this straightened out before I buy and ruin a set of new winter tires.
Thanks in advance!
