I believe the brake issue applies to those combinations that exceed the 3%. Here is an excerpt from Tire Rack;
"And finally, the maximum Plus Size applications for pickup trucks and sport utility vehicles result in wheel and tire combinations that are significantly heavier than the vehicle's Original Equipment (O.E.) tires and wheels. This increase in weight can lead to longer stopping distances, as well as increased suspension and brake wear."

There are a couple of tire size calculation sites that mention exceeding 3% could lead to brake failure.
1010tires.com; When changing tire sizes, we recommend staying within 3% of the diameter/height of the original tire. Any more than this and you face the risk of brake failure.
sizemytires.com; You should never go beyond
3% of the original
tire, otherwise you run the risk of brake failure.
I don't know why 3% seems to be the magic number. Perhaps it has to do with weight tolerance. I personally wasn't aware of that number until I started playing with the tire size calculator when looking for my initial Winter wheels and tire for the 2011 Ex I had.
On the 2017 and 2017 models you can, with the right tool, go in and select preprogramed tires sizes that will update some items such as the ABS module to account for the tire size change. This has been mentioned in a couple of posts.
