tbh i don'tlike any suggestion that means you keep any of that tyre set up. 4.09% is pretty bad!
I guess you'd be going for
REAR: 245/40 R19, which is 0.13% different from stock
and if you were sticking with those rims i'd get the front changed to
FRONT: 225/40 R19, which is 0.44% different from stock
