This is what I have learned from researching the best tire pressure to use talking to the tire experts.
3. So what is the best, Ideally you don't want to exceed the Max Load Rating for the tire under hard braking, If you do it is like under inflating your tires to 25 psi which is bad and even Waldo doesn't think that is good. Interesting that at 35 psi you can't step on the brakes hard and not go over the Max Load Rating for just a driver and gas in the car. Curb weight 3668 lbs + 14 gal. 84 lbs + driver average weight 180 lbs = 3932 lbs x .70% = 2752 lbs braking weight for the front tires. Front tires are only rated for 2734 lbs, but at 51 psi pressure their rated at 2866 lbs, much safer and shorter stopping distance.
You didn't learn any of this point #3 from tire experts, you are completely making it up in your own head. The situation of "overloading under braking" is just not a real thing. If it were, every car on the road would be blowing out tires at every stop light. The design and testing process of establishing the load ratings already accounts for this. There is no "safety" risk of running an FFH at 35psi and no "safety improvement" running them at 50psi.
You have no data supporting shorter stopping distance. Even wear does not correlate 100% to maximum grip. As I said above and you still are ignoring, even wear just means your contact patch is good from left to right. But higher pressure means it will be shorter, which reduces the amount of rubber touching the road overall, which means longer stopping distances. There might be a sweet spot somewhere above 35psi and below 50psi where the maximum stopping distance is achieved, but it's going to be different for every tire, every vehicle and every road surface. Without any real data we have to make generalizations and every tire expert will tell you as pressure goes up, grip goes down (within the normal range of the tire).
BTW the wear on my FFH is pretty even and I've always kept them in the 35-40 range. Only have around 40K miles on the car, so too early to say what the life will be, plus I've had one replaced due to puncture which has prevented me from rotating them in a "normal" routine.
