yes they are 20s, but its not just that... 305 wide too and run flat
Its the joys of living in the middle east.
Plus a tyre that is so rare, because basically only two cars use them, the ZL1 and the Shelby GT500

The tyres are $300 each in the US, but I'm paying the equivalent of $900 a piece here due to import etc...

Anyway they are on and i'm enjoying having grip again.
I'll post up pictures of the old tyres later...
they were a mess
