The LT will be far superior to the P rated tire, period.
That, I agree on. It will be superior at least to some degree in certain parameters.
We are talking load right? not traction, ride, etc...
My point is that hardly anyone NEEDS a superior tire than what the vehicle is spec'd for from the factory.
If a person has a truck and never even nears the load rating of the tires on it (which is the vast majority of owners) then they don't need a superior tire.
This is a numeric fact.
If one has a preference to overkill, that is their preference, but it does not make it a need or even a good idea for others.
It could be waste for them.
Like putting a class 3 receiver if you only pull a 4x8 metal trailer.
You personally might say why not have more capacity if you ever decide to tow more? Logical, bu their decision. I am not going to tell them they are crazy or wrong or unsafe to do so.
But that is probably apples to oranges again to you. You sure are hung up on fruits.
If I had noticed your sig earlier I would have seen that you like overkill and customization.
Should everyone "improve" their lighting and lift up their truck even if they don't need it?
Peaches to nectarines??? Different strokes for different folks but if all within specs...all are factually safe.
BTW nitrogen in tires is a big sales gimmick joke too. They can argue back and forth all day but in approx 99.88% of time, the only difference is slightly less air loss over time. Good condition tires and rims lose very little pressure anyway so N is never needed...just a personal preference or push or add on from a tire place.
