try the rene herse...it will give you a range, (me at total bike and me weight of 260 and 23 mm tires range is 82 to 67 change it to 28mm and it is 85 to 105....and 25mm I blow up the calculator) but bottom line is you need enough air to support the load

also to remember one of the original motivations was for large MTB tires running low pressure to avoid pinch flats in tubes
