Differences between Wheel/Tyre 1(245/40/18) & 2 (275/30/19)
Rolling Radius -2.8mm
Circumference -17.59mm
Diameter -5.6mm
275 comes out smaller overal in the above 3 areas, thats what is confusing me....anything im missing?

You're obsessed with circumference, which is ultimately irrelevant unless having a speedo off a miniscule percentage is a dealbreaker for you.
You should be concerned with getting a low-enough offset that your new, wider wheels and tires won't rub against the strut body. If you buy wider wheels but keep the same positive offset, the inner lip of your wheel will rest closer to the strut. Go too wide with the same offset and your wheel will hit the strut.
A lower positive offset moves the wheel farther outboard relative to the strut. That's why you see people going from 8.5 +46 to 9.0 +38 or +40, or to 9.5 +35.
