the suspension is very soft
causing abnormal wear when the car is turning at a rate faster than a snail
meaning the geometry is made to keep the ride supple not create a maximum contact patch of the tires
another thing is
if it is the rear tires going on the inside
if it is at the same ratethen i might even think that there is extra weight
do you carry alot of stuff in the car or ttrunk much
you may need to get an alignment with some kind of load in the trunk
or else the car willl wear alot when the load is added or removed
the wear you have is similar to lowered cars called camber wear
which is the iside of the tires going
but it is because the tires are angled at the bottom outwards causing it to run on the inner edges ,thus more wear
but it is great for added traction in a high speed turn
