Tyre pressures on 1988 ABI Marauder

[Pablo1]

My daughter has recently bought a 1988 ABI Wanderer 13/4. I believe this to be a dealer special based on the Marauder. The max weight on the plaque is 850kg. The tyres fitted are 155R13C 85/83N Enduro-LT.
Has anyone a specification sheet for this caravan showing recommended tyre pressures? Or, if you own a Marauder, what tyre presures do you use?
One tyre looks a little soft at the moment, hence my question.
Now, if I can encourage her to buy a spare wheel, I can sleep a little easier!
Thanks,
Paul

Everything you need to know.

Thanks, Damian. Looks like 39psi should be ok.

Hi Pablo, yes I saw 39 as being OK for the tyre and van weight.

Although 39psi is all but correct, it's a pure fluke?!
The safe maxiumum pressure on the tyre on tyresafe's list is quoted at 39psi for a maximum load of 850kg, that's because although the same size, it's a different construction tyre to the 'C'ommercial ones you have fitted.
Yours have a maximum pressure of 54psi and load of 1030kg per pair, but as it happens, the correct pressure is still actually 40psi for 849kg
