Proper Tire Pressure...
I am changing all my tires on out 5ver from STs to LTs. I have looked for an answer to my question but to no avail, so I will try here, you have all been helpful in the past. I'm going to put 80l...

I see at the bottom of page 1 that its a brocure of may 2008.
There is a lot of old information still standing on the internet.
Calculated the sise 235/85R16 the pressure/loadcapacaty list back to what power is used and it apeared to be power 0.7 wich is still used in America for C-load/6PR and up but gives to much deflection in the lower pressures/loadcapacity-range.
Also the different loadkinds like D to G-load are placed in one list. wich is also wrong. In Europe for every Loadkind a seperate list is made. A stiffer tire ( higher loadkind)has lower loadcapacity for the same pressure. You can notice that by the steps around the fatt printed loads that are not in line whith the other steps.
Probably they calculated the whole list for for instance E load and placed the fatt printed maximum loads of the D,F,G in to that.
Made my own pressure/loadcapacity-lists and planted them in next map.
In time I can add other lists if what you need is not given.
So if its only for the needed pressure better use my lists.
They give lower so saver loadcapacity's for the pressure , mayby even somewhat pessimistic. Even lower then the European calculation to wich American TRA swiched over to for P-tires and XL for a reason as late as 2006.
I still not understand why they did not do it for C-load and up.
Open the PDF out of the USA map with lbs and psi given, that begins with the reference-pressure ( Pr)/pressure needed for the maximum load/maxloadpressure ( that 80 psi in TS tires).
it is grooped by given per tire( as is usual in America) and given per axle single and Dual ( as is done in Europe). so you dont have to do the division yourselfes ( deviding axleload by 2 or 4).
Then search on loadindex or LBS maximum load in the first colom and use the list behind it as you are used to of the other lists.
Leftclicking opens it in the browser, but rightclicking makes download to your computer possible.
