Tire Cupping on the ZR1

[DRM500RUBYZR-1]

Most common causes are out of balance or failing shocks, but there are others.

A very distinctive wear pattern.

The "cupping" on my corvette tires is really not that visible in the photos below on the inside or outside of the tread of each tire.

One other cause which I shall check is Toe Alignment which is obvious how that might cause tire wear.......
Toe was excessive and reset to less than 1/8"👍

It is just difficult to imagine "cupping" or more wear every 4 or 5 inches around on the tire circumference



I expect that if one front tire is cupped it is tire balance.....
If both front tires are cupped it be Toe Alignment.....
Or other issues may cause one or the other tire to be cupped.....

In the photos above I do not see the cupping on either tire..... (I am not going to remove the tires to get photos of the inside tread which is essentially identical to the photos above)
