Tyre Label Query?

[ColinForsecks]

Is there any reason why the tyre size 265/35/R19 would be rated a C for Wet Performance whereas all other sizes are rated A? Is this just an error or is there a specific reason why they wouldn't perform as well?

Surely they wouldn't test every combination of the tyre during the tyre tests?

Can't quite make out what the symbol says but that looks like a specific fitment size so quite possibly a different compound to meet the manufacturers requirements. The 255/45 R19 is also a specific (Merc) fitment and rated differently. So yes, they probably have to test those separately.
