I looked in the Goodyear list because all tires of same sise should have same maximum load for same speed.
Found there G-load AT pressure 110 psi single 4540 lbs and dual 4410 lbs maximum load
When I calculate this back to 80 psi with European used official formula it comes to 3518S/3418D so pretty exact the 3525S/3415D you give in your opening post.
so Bridgestone gives a right pressure/loadcapacity list, at least best that is used officially. I use a even saver formula that leads to lower loadcapacity for the pressure and comes closest to laws of nature.
So these are the values I will use in my calculator and give a picture of it here.
Will put in an edit or next post.
