Hey guys,
All vehicles regardless of makes, do develope their electronic measures of cars based on their manufactured spec.
LSD, suspension, engine throttle, and other ECU controlled features will be basically working as "what manufacter intended" when you are keeping all things as state as it came.
Tire sizes will be one of the component as well.
However, remember that a lot of different model vehicles do offer different wheel sizes but they will relatively change their tire sidewall profile so that rolling diameter of vehicle will not differ much. They set about 1 % (or less)of difference of rolling diameter will not alter the driving characteristic of one vehicle and will not give much stress on ECU controls and other physical components. (Same thing goes for AWD, xDrive. If you wish to go with staggered wheels + tires setup front and rear, engineers recommend you to stay within 1 % difference of rolling diameter front and back).
If you do go over this 1 % boundary, you could potentially run into "different driving characteristic from what manufacturer initially intended".
All makes do spend tons of hours to develop their car and when it comes to sports cars that requires precisely measured values and input, they will spend more time for research to decide what they will do before any vehicle released for sale. But, of course, they are not perfect.. resulting recalls and extensive repairs, etc.
Going back to the topic, 245/35/19F + 265/35/19R and 255/35/19F + 275/35/19R does make their different in rolling diameter about 1.07 % front and 1.05 % at the rear. And I would not consider this as "major difference" for ECU control measures and driving dynamics.
