.. always on the inflation pressure ....

What are your actual axel loads or maximum axel loads; What pressure are you currently running at F&R; what is the load rating of your tyres & your tyres maximum psi???? a 4 part puzzle
On my Touareg with 265 wide tyres I carried out some tests with pressures and got a more even wear across the trye with +2 psi over factory recommendations.
On a race car my mate has they work them out with a temperature gauge used in 3 spots across the tread.
If you want you can increase it anywhere up to the maximum on the tyre but just looking at them doesn’t tell you what is happening at the contact point. Plus you need to compensate for loads carried and the ambient temperature.
In the desert we lower the tyres down to 1 bar but you wouldn’t try and corner on a road at that pressure.

my Cali is an Ocean, the Nokian Weaterproof 109 / 107T ... inflated them as expected on the VW plate ... now 3.5 front 3.4 rear .. with these pressures the summer tires (Conti Van200) after 15000km are perfectly worn without problems ..... Nokian tires, excellent in all cases, seem to me visually a little sitting on the hips, especially on the front .... until now I have followed the VW specifications, but I wanted your own opinion, experience ... thank you
I also run Nokian Weatherproof tyres as well. Mine are 235/60/17 with a load rating of 106XL, I actually run mine with a slightly lower pressure than the pressures VW show on the door jamb, because the tyres have increased load capacity over the standard 103.
3.5bar=51psi.
Are your tyres defiantly 215/65/16, when I googled that size of nokia weatherproof it came up with a 102 load rating?

This is the side wall of my Nokians, Max load=950kg@max pressure=51psi
I use this info to down air my tyres a little, I run at 42psi but i don't run fully loaded ever, and everything is better imo in terms of road holding/handling/comfort etc etc. only fuel efficiency will probably suffer a bit. The door sticker says 45/44psi for 235/55/17 on my Caravelle at full loading
What do your tyre walls say?

2250lbs = 1020kg = 109 load rating roughly @ 70psi
So on the face of it, you could increase your pressures if you feel the need to upto 70psi, and still be in the safety limits of the tyre.
The down side can be lower grip levels; more bounce; less precise straight line stability; uneven tyre wear etc etc.
It might be worth a trip to a weigh bridge to get your front and rear axel loads in running order, with your normal passengers/water/fuel/gas/items etc etc in your T6. I guess your maximum axel loads would be around 1610kg(ish), your VW handbook should confirm this.
There is a method with a tray of wet sand looking for even imprints in the sand to show how even your tread wear will be.
Some tyre manufactures will you advise on tyre pressures for certain loadings.
Roughly speaking if your tyre at 30psi would support 500kg (car loading), and at 70psi support 1020kg;
Your loads are 1620kg/2=810kg per wheel roughly:
Then each psi above 30psi supports an extra 13kg.
So to support 81okg that would be 30psi + (310kg/13kg/psi)= 54psi
I don't feel qualified to advise you any further, email Nokian Technical and see what they say
But on the face of it you may be right, but please don't take my word for it.

.... you're very strong !! ... I do not come to your reasoning .... it will be my age that no longer gigabite to the brain ... I knew the proof of the imprint on the sand, or the color on the tire ... and it works !! ..... Another problem, not less important, is also to see the money spent that is consumed badly .... Thank you very much
