You can not compare what others use, with your situation.
For instance 007 also chanched to bigger sise with the E-load, wich yustifies a lower pressure.
If sises stay the same, you need a bit higher pressure for the same load. In American pressure/loadcapacity- lists the different loadranges are given in one list, and that is wrong.
European tiremakers give for every loadrange a seperate P/LC list .
To be short.
What you need for determining the right pressure is real weights on tires, maximum speed you use, and wont go over for even a minute, together with the tire- specifications 3 things.
1 maxload or loadindex
2 pressure behind AT on LT tires best, but loadrange stand mostly for a sertain AT pressure.
P tires only give max allowed cold pressure and comparable AT pressure is lower.
3 maximum speed of tire or speedcode.
Especially determining the loads on tires is the most tricky part in it all, often yudged wrong and if to low yudged can lead to blowing tire or treath-seperation.
Best is weighing per axle-end , 2nd best per axle, in the loading you use. Vehicle makers use the GAWR's to calculate the advice/prescribe- pressure, and often for max technical carspeed.
Noemal use is often only driver and a little load, then axle loads rear much lower. Load on front stay about the same in every loading.
This " pigheaded Dutch selfdeclared tirepressure- specialist" can help you with this . Give as much possible info you have , and I will calculate, and show where the limits are with that advice.
