What causes the cupping of tires?

Bad alignment. Over-inflation of tires. Worn parts...

Cupping!

Cupping is where the Rubber meets the surface and they take on a Cup!
Just like here tomorrow night when the Cunucks are going to keep the cup.

x2. All three of those have been the culprit for me at one time or another on various vehicles.

We might add wheel(s) outa balance to that list also right? I'm not sure I understand how over-inflation can cause cupping though. I do know it can/will cause the center part of your tread to ware more rapidly, but 'cupping'?? 'Splain that to me please..... thx.

Bad shocks will cause tires to cup also.
