sorry to bore you all with another tire pressure question,
just bought my 2nd van, a abi cae ambassador, had the wrong tireson so went to my local tires shop.
he recommended 155 r13c witha load rating of 90
these tires are fine for my van but its the pressure noone can tell me,on the charts at tiyresafe.org they dont list 155 r13c so that was no good,but i did find a formula that is supposed to give a good psi
this is how i did it
mtlpm=1100 kg
max tires press= 65 psi
max tire load= 600kg x 2
the unladen weight is 805kg, the mas laden weight is 1100kg, this is from the plate outside the door.
all that will be in the van is an awning, empty water carriers,a little bit of food and bedding,the usual crockery and utensils. gas bottle is too big (19kg) to put in van so it will be in the boot of towing vehicle
I have never really understood what a van manufacturer includes in unladen weight (MIRO) - spare wheel ? battery ? gas bottle ? etc.
However, you seem to have a very generous payload allowance of 295kg and I would be very surprised if you would get anywhere near 1100kg fully laden. So, 60 psi will be fine.

I have Swift Challenger 400se with same size tyres and Max laden just slightly under 1200 kg and handbook states 46psi on light commercial tyres, which I have.
