Tire Pressure?

I apologize for my rude remark...it was uncalled for. I understand you're providing the best info you can, but your explanation is difficult to read and comprehend. I hope others have understood better than I.

I think the American expression is "no offence taken"
I get these kind of remarks more often .
But my post has 3 parts.

1 is to get the exact tires and kind of vehicle right.

2 is the part you dont understand about the universal used formula all over the world wich has a power in it, and the different powers used in American and European system, and that to laws of nature this should be one power. This power formula was introduced in 1928 for diagonal tires with power 0,585 and was meanth for the tire-fitter to use a simple formula to determine needed pressure, but totally missed its goal because almost nobody understands the power part in it. Europe chached the power for radial tires to 0.8 for all kind of radial tires about 1970 and America to different powers of 0.5, 0.65, 0.7 and as late as 2006 chanched the 0.5 and 0.65 for P-tires and XL to that of Europe of 0.8. For C-load and up ( LT and truck tires) America still uses 0.7 power.
This all to calculate loadcapacity for a pressure.

3th part is the copy of text I used in other topic to show wich data are needed from tires and vehicle before we can calculate.
