I've noticed for a while that my 2 rear tires are cupping/feathering (not too sure which term is correct) on only the inside of the tire. I think it's cupping because the surface is not smooth when I run my hand through the tread. The thing is, the tire has a lot of treadlife left and no visible camber wear even though I'm running about -2.6. After researching a bit, I noticed many makes/models of cars and even motorcycles also have this problem.
I'm running Falken FK452 but this happened to my 2 rear Kumho tires that I previously had before too.
Possible Causes?
1) Worn shocks - my Tein SS are old and is wearing out but I push down the trunk on each side to check if it bounces and it only rebounds once so I assume that they are still OK at best.
2) Teins have such soft spring rates, which leads to a lot of bouncing on the road, could this be why also?
3) Camber/toe issue?
What else can cause this or are my coilovers most likely the cause?
Has anyone experienced this that can chime in?
Here's a pic I found online that looks almost exactly like my problem.
