Evidence on my tires that pavement is contacting just beyond the tread pattern is visible, but that is not what i am calling feathering.What are you calling feathering? You can simply see that the rubber has met the pavement?
Feathering is a term i learned as a tech.
As per bridgestone: "Tires are “feathered” when the tread ribs are worn lower/smoother on one side and higher/sharper on the other. This is often caused by a combination of improper alignment settings, such as excessive toe and caster."
It is not subtle in my case, but not horrid yet, easily felt with hand and i have a lot of road noise, road noise increases after warm.
I will try to get it down for an alignment next week. We need the car while i am repairing the others.
