i believe either your tire is a bit hard for your track. usually softer tire will give you cone shape with smaller diameter on outter edge and harder tire will give you cone shape on inner edge of the tire.
Yep, this is quite possible.
The reason it happens is that with softer tyres, you have more total grip, the car rolls more and you end up with tyres coned outwards.
With harder tyres, there's less grip, less chassis roll and the tyres can cone inwards.
Adjust all settings accordingly.
