10R80 Red Zone
Someone with access to the technical manual posted on another topic.
Red Zone on 10R80 starts at 302F.
Yellow zone is not stated. I know people have approached 250F without hitting the yellow zone.
I have asked him to look up the 10R140 and see if the 223F (Top of normal zone) and 302F (Red Zone) coincide. If so it would be a fair guess that the 265F Yellow Zone also coincides.
