what is the tread depth on a brand new Pilot Exalto 2?

Just trying to see how much wear there has been on the tyres of a 182 i've been to look at, but can't seem to find out how much the tread depth on a brand new tyre should be, so i can figure out how worn they are.

Many thanks

Roughly 7-8mm at a guess.
