There certainly must be more stored energy in my 19.5 wheels and tires compared to the stock 16's when at speed but I never noticed any braking problem. Well... just once and it was during a very steep descent from over 11,000 feet and NOT having an exhaust brake (with stock wheels and tires) which prompted the exhaust brake installation.
With the exhaust brake I have never experienced brake fade again no matter how loaded or how long or steep the grade, including places like "The Grapevine" , Cajon Pass, and worse. Of course I insist on all wheel brakes on trailers.
I have about 70,000 on this set of Michelins and I will retire them due to age and concern for invisible deterioration before they are worn out. High mile drivers with a similar setup report 200,000 miles on a set.
